Q
I want to remove the rear indicators from my 98 535 virago & reposition them further back on the mudguard to
accommodate my pannier bags. I realise I need to lengthen the wiring but was a bit stumped on how to get them
off. Having removed the pinch bolt the outer part that holds the bulb didn't want to pull
off, not wanting to break the wires I left the job until I'd picked someone else's
brains. Just in case it was soldered to the bulb holder !!!!!! .Any tip would be
appreciated.

Q
I’ve been riding my 1986 Yamaha Virago XV1100S for about 4 months now and
notice the red light problem and now I am kind of feeling better that it may be
a design flaw and that the sending unit may need to be cleaned every time the
oil is changed.
Q
Hi. I have a Yamaha XV1700 Roadstar Midnightstar Silverado and on the transfer oil filler plug is a grove to remove it when you change the oil. Can anyone help me to what sort of tool that i require thanks Colin Q Can anyone help?? I tried to change the headlight bulb on my XV1100.. thought it was the 2 screws on the headlamp rim needed taking out.. wrong! I undid them & 2 springs & a kind of spring clip fell out. I now assume it's the single screw to the left of the lamp (as you face it) I should have taken out... but how do I get it back together again?? I can see where the springs go, but can't get them back in, but I don't know where the clip goes. Alan
A
There are two removal screws in the lamp reflector at about 4 and 8 o’clock positions. Once you have the lamp surround out you should be able to work out that the spring goes onto the long screw which then passes through a bracket and nylon nut. The two screws are then holding the lamp unit within the surround and the clip is used to finally secure it on the opposite side. This allows the lamp unit to move both vertically and horizontally within the surround to adjust the beam position.
Q
I need to take off my rear tire. It is a 1985 Virago 1000. shaft drive. I would love to know how and any tips I need to do this job. Heck, all I need to do is put on a new tire but here in Orlando, Fla. they won't work on a bike that is over 10 years old. This place sucks as bike repair. Oh well, if you can help I would be thankful.
Q Hi, Can any body help with this question. I have XV750 (96/97) with wired spoked wheels, I would like to replace with alloys. Will alloyed wheels from an XV1100 fit without too much trouble? Regards William Hinder of Yeovil No. 5606.
A
I’m advised that the alloy wheels from the XV1100 are a straight fit onto the XV750 after 1994 (UK) with the caveat that the front brakes are different on some models so check the dimensions very carefully around that area. Q Hello. I need to replace the rear tire on my xv 750 virago1987,my question is how difficult it is if I want to replace the tire my self? I do have compressor and some tools to do the job but is it difficult to remove the wheel from the motorcycle? The size is 140/90/15.Thanks in advance, Tony A
Tony, It’s certainly possible to change the tyre yourself but bearing in mind the performance of modern bikes and the safety aspects involved I wouldn’t recommend it unless you REALLY know what you are doing. There are also balancing issues. I buy my tyres direct and take the wheel and new tyre into a local shop to fit them, they charge me around £5 including balancing.
Q
Jet Kits for XV535. I’m sure someone out there will have done this. I want to put straight through pipes on my XV535 DX Model Year 2000. I believe that I will need to re-jet it. The problem I have is that I can only find jet kits up to model year 98. I’m not sure what has changed between models but… Q Hi, I am thinking of buying a XV 750 but have restricted access to garden and Garage (28" doorway). I read that the width is 33" but guess that this the handle bar width, which means I should be able to get the bars through but I am worried over the width of the rear indicators and front footrests. Do you have the width of these two items as they seem to be the widest point in the pics after the handlebars.
A
Hi. I have just measured the wife's 750 and it is as follows:
Q Does anyone know if a 1983 Virago 920 can be towed at high speed (65 mph) behind a car on the rear wheel? I am looking at a motorcycle hauler that picks up the front wheel. Will it damage the tranny?? A Are you mad? You are not allowed by law to tow anything at that speed.. tosh c12 A
Tosh is absolutely right, the best you could hope for is to be stopped by the Police.
For the record, in case you thought of towing at a more reasonable pace, you would most like wreck the transmission. All the oil would be pushed to the back of the axle leaving the gears at the front nice and dry.
All drive shaft drive bikes should only be towed with both wheels off the floor.
Q
Hi. I have a Yamaha Virago 550 (1998) making a rattling noise. Checked chains, clutch rubbers, can't find the problem. Done 12,000 miles. My mate said put a cut exhaust on, to drown rattle! Anyone got a cut exhaust or an idea what problem is? Cheers. A
Tony. If the rattle is coming from the top end of the engine, check the valve clearances for excessive play. If the rattle still persists, reset the camchain
tensioners. I suffered a top end rattle for a week, despite setting the valve clearances correctly. resetting the camchain tensioners cured my problem.
Q (cont)
. Hi Simon, I forgot to ask, did your bike sound like piston tapping at the top end? Mine sounds like this. Yamaha told me at 12k, the chains should be ok, my mate took the full plugs out on the tensioners to see if they were stuck, the tappets were a bit loose, but this has all been done and it's still noisy. When I put the bike in gear, then let the clutch out, the rattle gets worse. I thought it might be the clutch, at the end of the day, it still sounds like high front piston rattle, any idea?
Q
I recently bought an XV 535. It has a fuel tap mounted on the bottom of the Lower fuel tank. This is not mentioned anywhere in the hand book! It is shown in the Haynes manual as a schematic diagram, but nothing further is mentioned about it. It has a cable (pair) connected to it. When I turn the tap to the off position fuel leaks from it! Does anyone know any more about this device ?
A
Yes, The manual fuel tap is between bottom tank and the electronic reserve solenoid which is controlled from the right hand handle bar switches. When you operate the switch you should be able to hear the solenoid click. The manual tap can be refurbished using a tap repair kit and is an easy job. Cost approx. £13.00 inc. postage from me if you want one. No need to remove the tank:-
(In my case I actually took the tank out and completely dismantled the fuel tap and solenoid Assy. It was just seized up with dirt/rust etc. Complete clean and lubricate and then all Worked fine! no parts needed.)
Q Hi. I have a techy question regarding XV750 restriction that I couldn’t find an answer to on the FAQ section of your website. I have acquired a lovely condition 1985 Virago XV750. My intention is to pass my full test on my little 125cc chicken-chaser, as when I tried to do the test on an ER5, I had major problems ‘Progressing’ – not a prob on my little 125 though… The obvious answer for me was to get the Virago restricted for 2 years.
I am told by a very reliable bike mechanic near me that there are only kits available for 1995+ models, and that they cannot get the paperwork for the restriction to make it legal.
Have any of your members come across this problem before perhaps? And if so, is there a solution? The bike has a great deal of sentimental value to me and don’t wish to change it. Don’t want it sat rusting for 2 years either…
Many, many thanks, and looking forward (assuming this setback can be resolved) to become one of your elite very soon…
Q Hi I am wanting to fit a restrictor kit onto my virago 535, I have been offered a restrictor kit out of a 750, and told that they are all the same, does anybody know if this is right? will it fit my 535? etc, Or is there anybody out there who knows were I can get a restrictor kit from without having to pay garage prices, HELP!!! Thanks Sandra
Q Hi, hope somebody can help me out here...sorry for the long email but I thought
I'd give as much info as I can. A Hi Dave, I just bought a 535 which also has an FI certificate. This raises many issues which I was not aware of at first! Whilst I had the certificate, it is supposed to show the current owner or riders name on it (they FI say!). FI say you must have it checked by a Yamaha Dealer to confirm it is still there (if on 33bhp like me) They say you or the Dealer must then forward this information to them and they will issue a new certificate and charge you £25 for the Privilege ! So I took it to my local Dealer is has a good reputation. They took the bike in the workshop and told me “Yes, it is restricted” ! Question, how do they know this? The guy explained that there is a restricting plate or washer I guess in the air intake to the carbs ! S0, I got them to sign and stamp a letter I had prepared to confirm this, which they were quite happy to do.
So there are two interesting points here, 1, did I see this device = No ! , 2, and then why should I have to tell anyone else when they have
confirmed in writing that the bike IS restricted against my name. As I assume this is what would be required by Law, that’s it as far as I can see.
Perhaps there are some Legal people among our membership who can confirm this for all of us.
Strange thing is, that a guy at the club said his 535 was restricted within the exhaust system, so this is all very confusing.
Regards, John. A Hi I have just read the thread about restriction of a 535 I can't really answer it other than to say that my restrictors consisted of two identical washers.
Something that may be of interest to other bikers though that need to have their bike restricted to enable them to ride it on their licence is, check with your insurance company before spending out loads of money on having restrictors fitted at a garage, I was quoted £200 to have my Virago 535 restricted so I contacted my insurance company Ebike and they said as long as I had proof that the output of my bike did not exceed the 33bhp allowed on my licence they didn't mind who or how I had it done as long as I could prove the BHP. To this end I then emailed most of the VSOC centre reps to ask if any of their club members had taken out restrictors and would be willing to sell them on. I had several replies and bought mine from JT from the Yorkies, then had a friend from my centre fit them for me and had a Dyno reading done on the bike to prove the BHP so for saving of £130 I now have an
insurance legal 535 on the road. Q I have a J reg Virago 750 which leaks petrol into the sump. It runs well and does not burn oil. Any suggestions how I can stop this?
A
I had this problem on my 125.
Eventually the problem was traced to the fuel pump, which it doesn't really need unless you run the tank right down. A The spring in the petrol tap corrodes and lets petrol get past. Eventually it gets past the needle valves in the carbs and floods them, petrol then flows down the bore into the sump. To check this is easy. Disconnect the fuel pipe from the tank - it should self seal. A vacuum pipe off the engine keeps it open and shuts when the engine is turned off. (XVTRALERMAN)
Q
. I wonder if anyone has had this problem before? I own a 1999 Virago 1100 with only 2200kms on the speedo. The other day I ran out of gas without the fuel light warning me. I tried the handle reserve switch but it did not work. I cleaned the switch, emptied the tank and ride til it ran out of gas and again no warning light coming on. Weird, as two months ago it was working fine. I cleaned most gas components including the gas filter. Can any Virago owner tell me if they have experienced this problem before? Is there any sensor elsewhere since this is the only motorcycle I know that has an electrical reserve switch v/s the normal manual one? Thank you, Mario.
Q Hi I have a Virago 535 1995 model, I have not long passed my test and got a shock after the bike started slowing down and spluttering (yes I ran out of petrol). I turned the petrol reserve on and tried to start it, only to discover either the reserve did not work or it clicked in automatically without letting me know. If it clicked in automatically is this normal, because I can not see the point of having a reserve if this is the case? I am wondering if this has happened to other virago owners, or could it be the reserve switch broken? A
I am not sure how long ago you posted this, but I am having the same problem with my Virago. After removing the fuel cock assembly from the underside of the lower gas tank (above swingarm), I found that a part was missing. On the fuel cock there is small tube that sticks up. This tube is the “main” fuel draw pipe. In theory, when you switch to the reserve, there is another hole in the fuel cock assembly next to the main pipe that will draw fuel. The main fuel pipe is elevated so that you can empty the fuel tank to the top of the main draw pipe. Once you flip to reserve, you are drawing fuel from top of the main fuel pipe down to the bottom of the tank. I have attached a parts catalog and a print of the specific page of the parts catalog that shows the fuel cock assembly. I am going to take my tank out of the virago tonight to try and shake it to get the main fuel pipe out. I think it just fell off the fuel cock assembly, so the fuel is being drawn to the bottom of the tank no matter what position my switch is in. I did check on the price for the fuel cock assembly and it is $220 US dollars! Hopefully, I can fix it on my own. I hope this helps, and good riding to you. A
. I had exactly the same problem and found it was indeed the reserve switch. (Although with mine it was back to front, Res was normal and normal was reserve). I think that the switch had broken so the previous owner changed it over so it was on permanent reserve.. Bloody nuisance or what!! Anyway, a quick visit to EBay and got a new handlebar switch for a tenner, problem solved. A
. I
had the same type of problem. You have to remove tap and take off rear cover, then give the plunger a good clean then grease everything up put it back together.
Now when you flick to reserve there's no mistaking the tap switching over (loud clunk),
the initial prob seems to start either because of jet washing or wet weather spray onto tap which is assembled dry,
I did as above and had no further trouble my mileage per year was an average 60,000 A
. I've had a 535 for 14 years now and ran out of fuel regularly in the early days. The problem is generaly not with the switch on the handle bars but with the solenoid valve fitted below the fuel tank. Because of its location low down it gets attacked by all the road grime and seizes up, thus not moving to the reserve position. Unfortunately it's a messy job to get at it. Haynes manuals recommend removing the tank via the side of the bike but I was advised by a Yamaha mechanic at one of our rallies that it is easier to remove the rear wheel and lower the swing arm to get at the valve. This does unfortunately mean that, when you get the valve off the tank, you spill all that reserve fuel on the floor. I've done this twice now with the same valve over the years but it's now failed
again and looks in bad condition. I've got inyo the practice of filling up every 70 miles now, just in case!
TIP.
With regards to the replacement of the reserve solenoid switch fitted to the base of the lower fuel tank on my 98 535
Virago. I had occasion to replace it a couple of weeks ago & according to my Haynes manual it was going to be a massive job. After following the instructions to the letter I got to the last thing & that was to remove the lower fuel tank, for some reason it just would not come out as if something amongst the mass of electrical wireing was stopping it. Q . I ride a XV1100SE with 10k on the clock. Only recently bought bike. It is a 1999 model, my problem is this: when closing down the revs I am hearing a whine that seems to be coming from the drive shaft. As long as the throttle is on turn, no noise, only when coasting in gear. If I depress the clutch, the noise goes away. Can any one help.
A
. Hi. Your question regarding the noise on your Virago... Unfortunately, the low mileage bike (average 1K per year) hasn't done you any favours! The problem is likely to be a dry bearing in the front shaft end in the gearbox. The reason this occurs is due to the lack of use or running of the bike regularly and I suspect the bike had sat a while without use. The cost of the strip down will be substantial if done by a bike shop mechanic due to the oil, gaskets , bearing and mostly labour. Q . I have a XVS1100 with 10k on the clock, when the engine is hot and you slow from a cruising speed to 30-50mph there is an odd sound comes from the front of the engine it is not affected by pulling in the clutch, or weather it is in neutral or in gear, a quick jab on the starter button or revving the motor, and will appear when you are stopped and disappear just as quickly sometimes with a flick on the gas, has any body come across this to give me some clue before I start stripping down. A
. I had a similar problem with my Dragstar XVS 1100A at about 8000 miles with a noise coming from the engine noticeable at low revs. I found that the starter solenoid was stuck and the starter was still turning. By hitting the starter button or revving the engine to cause vibration may be releasing such a problem. If it does stick and you do not notice, it will overload the battery and at night will flatten after 30 - 40 miles. The starter clutch allows the engine to go faster than the starter, bit even though it all runs in oil the starter clutch will wear.
Q
. Hi all. I have Virago 1000cc 1984 which I bought for $2500.00. I have since spent heaps on re-chroming. It has done some 94000 k's and after riding for some k's has developed a timing chain noise. Can anyone tell me the steps on how to adjust the tensioners.
Q
. I've got a 1990 XV1100.. bog standard, great condition BUT the engine is knocking like the big ends have gone... Is there an inherent weakness in the bottom end or main bearings?
TIP . The owner of a 535 Virago (1998) complained that the engine intermittently fired on one cylinder. After much fault finding, I eventually found that the wires from the loom - just before they go to the coils - pass over a thin bracket. The bracket acts as a guide for the wires, but the bracket had rubbed away the insulation. This allowed the ‘make a spark’ signal to be shorted to ground. A piece of heat shrink sleeving over the worn through insulation fixed the problem. Whilst poking around, I also found the connector to the coils to be almost completely corroded. (Bear in mind this is at the front of the bike, so road muck gets blasted to this area by the front wheel. A little plastic cover prevents some of the ‘blast’ but not much. In addition, the plastic cover stops anyone washing the area to remove any road salt.) I had to remove the original connectors and solder on new ones. Cleaned the (coil) spade terminals with emery paper and washed them with alcohol. Reconnected everything, and the engine ran without any problems. In an attempt to stop further corrosion, I sprayed the coil connector area with Waxoyl.
Q
. Yes I have a problem I have a 1986 Virago 650 and I am trying to figure out a problem. My front spark plug is always clean but my back spark plug is always sooted up, must clean it up every few days. Does anyone have a knowledge in this matter
Q . Having just pushed my 97 XVS650 Dragstar home on the night of Sunday19/12/04 due to a strange phenomenon never before encountered. At about 22.45 travelling at 50mph thru the road works on the M42 my bike started to sound and feel like it was running on one cylinder or just lost compression on one cylinder. It finally died at section with no cones so I sat for 5mins and fired it over low and behold it ran as smooth as ever so I continued home 300yds further down the road the same again so I shut down and pushed. When I got home I gave the bike the once over it look for oil spray (Head gaskets and the like) but nothing I've heard of carb icing but this seemed ridiculous as carb icing can happen in summer. Or was it just Ice in general was the Hypercharger putting two much cold air into the engine and causing the carbs to freeze or just the wind blast in general freezing the fuel in the lines and or carbs? (fuel still liquid in tank). Has any one suffered similar during winter it was approx 4 below freezing not including wind chill. I will update once I've checked the bike in the morning. A .I have got to the route of the issue I think/hope. Having stripped the carbs and confirmed the heaters are working and the coils firing correctly I cleaned all the connections on regulator/rectifier as the bike was still running as rough as nails at low rpm (higher rpm no probs). So I was left no choice but to speak to a mechanic who suggested the leads or plugs. Now having only recently put two brand new iridium plugs in the bike I did not think this was the problem but guess what - it was one of the plugs had stopped firing at low rpm (i.e. at tickover no spark) but at high load when the coils are firing harder lots of spark but very weak. Put the old iridium plugs back in and bingo lots of spark and more power! I will be keeping a very watch full eye on this as the plugs are £10 each. As for the coils and ignition this is due to change in the new year to Dyna adjustable ignition and better coils. Regards Rob Jones (Centre 8)
The problem has reoccurred 17/01/05 almost a month to date the bike spluttered to a halt on the m42 again this time it seem to most definitely be something getting hot as after stopping the bike carried on fine. I will be getting the Coils looked at ASAP and having checked the lead on the rear cylinder it looks quite heavily heated (blistering around plug hole) so will be changing these as well.
The problem is back with a vengeance having changed the plugs for something a bit hotter DRP9 instead of DRP7 on 18/01/05 the problem happened 30 miles into a ride and 15 mins later was gone. My Father who is a mechanic has come to the conclusion this is nothing electrical (Coil, leads, reg, ign or plugs). It only happens when the bike gets hot, very hot to the extent the rear cylinder head chrome trim is Blistering!. The rear cylinder is suffering from either major oil starvation or has picked up and not running square and is ceasing in the barrel, he came to this conclusion as his own bike suffered this problem. Ride bike at constant 70-75 for about 30miles gets it hot to the point the rear cylinder seems to cease, leave 15mins to cool and whoooo hoooo away you go as if nothing ever happened. Only a full strip will show the extent of any damage so will update this listing when I have more info. Regards Rob Jones (Centre 8) 5212 (p.s. bike is running bigger jets and V&H Cruzer pipes and a Hypercharger.
The over heating problem seems to have been narrowed down by our friends across the pond were they tend not to use the Hypercharger. A Dragstar specialist parts manufacture has possibly nailed the problem to the jetting and the speeds travelled. The Hypercharger is extremely difficult to set up even on a dyno as no air flow higher up the revs as bike is static on the dyno, as the bike is moving at 70+mph the fuel air mixture is way way to lean due to the ram air effect of the Hypercharger this in turn is causing the overheating possibly to the extent it is cracking the oil and causing the seizure which is why when it cools down it carries on ok as I usually keep the speed down to around 50mph no leaning out at this speed as the mains and pilots work together.
God dammit if the if that pile ** $%^& that Yamaha calls a bike has not only gone and stranded me yet again and these things are supposed to be reliable! (sorry rant over) my xvs650 has yet again come to a grinding halt only this time it failed to do anything but look good sat at the side of the road.
( 14/02/05) Hopefully this will be the last installment of rough running from me. As you know I have listed an essay of problems since Dec 04' I finally fitted the new coils and ignition a couple of days ago and this amplified the problem to such extent that I could not even get the bike off the drive before the misfire cutting out became a prob.
Final Answer ?
I never solved the issue with the bike and neither could the local Yammie stealership or mechanic. I have recently sold it on as a non runner due to the fault, the buyer has advised he managed to get it running eventually by changing the carbs/manifolds and refitting
original pipes from his other bike but he noticed that the rear cylinder is still overheating and spluttering occasionally so in theory it still has not been fixed
permanently.
Q
. I have just purchased a 1994 XV1100 and find that it has a nasty sound of a knock coming from beneath the fuel tank every time I hit a bump. I don't think it's the front shocks and you cannot reproduce the problem by standing still and bouncing the front shocks. I thought it may be tank rubbers but they are in tact and there is nothing loose under the tank.
Q
. I have a similar noise coming from the same area . I had the fork oil changed and thought maybe they used a different oil or added too much. I drained a small amount out and it seemed to lessen the noise but if I go over a fairly large bump it is still there. It wasn't there before I had the fork oil changed . What do you think is causing this? Ken...
Q
. I have a 2000 Vstar 1100, runs great but when I shut engine off it makes a very loud clunk almost as if the starter is trying to engage while engine is running. Any ideas what is causing this?
Q Has anyone out there fitted a tacho gauge to the XVS 650 or similar. I am interested in fitting one of the commercially available small 44mm tacho's to my bike but not sure whether to fit an electric or mechanical (if there is a drive for it). Any info appreciated.
A
I fitted a tacho to my XV535. I used an electronic tacho and mounted it by fitting the bracket under the handle-bar riser. Wildstar Internal Engine Noise Q . I've just bought a 2003 1600 Wildstar with about 1000 miles on the clock. At about 1600 miles, it's started making a mild grinding or loud whirring noise at low speeds in 1st and 2nd gear, just after moving off, usually with the clutch fully home, and this can be 'felt' through the bars. If you shut the throttle quickly it also causes the noise for a few seconds, again at low speeds. The noise is easily heard above the engine and exhaust. Same noise can be induced by intentionally letting the engine labour when it seems to synch with the engine stroke.The dealer I purchased from is 200 miles away and my local dealer, although helpful, has almost no experience of Wildstars, like me, to date. The only thing found was a slack drive belt otherwise all seems ok. Other than this, the bike is fine. Can anyone throw any light on this problem or is it a case of 'they all can do this'? Local dealer is happy to look at matters under warranty, if needed, but neither he or I know if there is a problem. HELP!!
A
. I am also the "proud" owner of a wildstar for 4 years and 30,000 miles. Does the noise you refer to happen if you open the throttle when riding the bike and then close it quickly ?. This normally results in a screeching noise, like a clutch problem. If so then its the drive belt tension. I've had this a few times and re-tensioning the belt fixes it. There is also information on a German site about problems with the cam shaft sprockets but they state that this is on 99 & 2000 bikes only and Yamaha are aware.
Q
. I've got a Wildstar 2000 modal from new 17500miles it now has started to make the same noise in the clutch but when its under load in all gears but when in top at about 60ish it goes if u pull de clutch in when accelerating or at lower speeds it will go as soon as u let de clutch out its back have had clutch spring and pressure plate changed the was some wear on de plates put as its not slipping they were never changed the noise is not as bad but still their when under load any ideas as needed t be sorted as its driving us nuts and the bike shop run out of ideas as well
I've been receiving a lot of requests recently regarding wiring of the wildstar for choppers, switches, inside the bar wiring etc. Now this is the best place to get the pictures and the key as you can download them without filling up your email box. Be warned, they are large files, but well worth it when you don't know what the heck is going on. The files are for the United Kingdom/European (1999) version of the XV1600A Wildstar, but they should help you out for most of the other models.

Q . Hi, I have an XV1100 Virago (1990 G reg) and a Dragstar XVS1100 (02 reg). I bought the Dragstar as I expected it to be a nice upgrade to the Virago but I find that the Dragstar is a lot slower. I know the Dragstar is heavier but I expected it to be nearly as fast as the Virago but it is not. The Virago can accelerate a good deal faster and has a higher top end speed than the Dragstar. Do you know what Yamaha has changed between the two motors to make such a marked difference? I hope you can help. Yours, Barry (p.s. I still have lots of fun on the Virago) A . I part ex'd my Virago 1000 E reg for a 1100 Dragstar I don't think my Dragstar is much slower maybe its geared differently. I know the Dragstar has some sort of rev limiter ( nice to know where to get rid of it) that if I try and cane it though the gears the engine tends to start spluttering just before you would normally change gear maybe that's something to do with it . I'm getting a Hypercharger fitted within the next couple of weeks and I will see if it makes a difference But I must admit I did expect a lot more it doesn't handle quite so well as the virago ,maybe its the rear mono shock. My trouble is what I really want is the performance of a sports bike but the look of a cruiser - suppose can't have both but can always hope . Regards Paul.
A
. I upgraded from an XVS650 to my 1100 VStar. Now I do not know about the performance of the 1100 Virago having never ridden one. I would suggest the Dragstar only feels slower but in reality it is not as I also ride a 650 V-Twin commuter which feels way quicker than my 1100 but it is not, as proved many a time. Even higher up the gears from 70 onwards the 650 stands no chance even if I am two up.
If anyone's interested in the Kuryakyn Hyperchargers ( www.kuryakyn.com/category.asp?bn=metric&cn=Air+Cleaners ), I've just fitted one to my 650 Custom and it makes a noticeable difference to the power - plenty of extra grunt on fast roads! Kuryakyn say it's relatively easy to fit to any cruiser except an XVS650 as they say the necessary re-jetting is quite tricky on that model. I got a local garage to fit it and it did take them a while. One last comment for anyone who sees those lovely US custom cruiser websites with their lovely low prices in nice weak dollars (e.g. my Hypercharger was $199 compared to UK price of £199 - almost half price!): don't forget that your lovely bike parts will arrive with a not-so-lovely bill from those customs and excise people... quite what Value they Added to that transaction is anyone's guess, but they'll still Tax you... Cheers Geoff
I've just fitted a Kuryakyn Hypercharger to my 650 Dragstar Custom with only a few problems. I know that Kuryakyn recommend the thing being fitted by a dealer or qualified technician. Apparently on USA models the mixture screws are covered with a brass cover which has to be drilled to get to them, whilst the European models, which mine is, have lovely, big, easy to adjust nylon screw heads. This might be one of the reasons why Kuryakyn make the recommendation. If you're not sure if yours is a USA or European model, you can just see the screws by shining a into the carb area, behind the air filter. There's a picture of the screws (idle mixture screw) on the ISRA link below.
Q . Can anyone tell me what battery I need for my Virago 1100? The current battery on is has the code GM18Z-3A, and I've been told no one can find this battery???? A . I have just fitted a battery to my 89 Virago 1100 it's a sprint power max. Y50-N18l-A2 it fits and works a treat!
A
. You can also use YTX24HL-BS or Y50N18LA. The best replacement is a wrapped glass mat gel filled sealed for life battery. They carry around 50% more cold crank power, work better in cold weather and can’t spill. But they do cost a bit more. See:

Virago owners who've had "the clunk". Q . Hi - My name is Tom Sullivan and I have a 1983 Virago. The problem is that the starter grinds when you go to start it. Can you tell me how to fix the problem or show me what I need to make to fix it A . The problem is usually the outer idler pinion and its friction clip. It slips and the gear tries to grind its way in. Go to "Starting problems" and my item. My name's Steve Westbury. Also an address for starter motors on another following question. Hope this helps Q . XV1100: When I hit the starter button, I can hear the solenoid, which pulls a fork assembly to "engage" the starter motor, go off like a rattley machine gun. I've found that if the battery is fully charged, then no problem, but if the battery is 10% below full charge, this "chatter" takes place. Before I go off and buy another new battery, does anyone have a solution to this? A
. So, Your Starter Is Just Clicking
Q . Hi, I have an XV920 and when I push the starter button it sounds like a bag of spanners being thrown on the floor, it starts no problem when it catches.

Whilst working on the VSOC stand at the NEC bike show I was asked if I knew anything about the Venture Star Top Box (or Trunk) coming adrift. Apparently there was some technical bulletin issued but the gentleman couldn't get his local Yamaha dealer in Leicester to understand the problem. Having checked over a few sites and enquiring further, I'm happy to give you all a link to a Venture Star web site that should help all those of you with queries of a technical nature on the Venture Star

Q
. We just bought a 1984 XV700 with 7k miles on it. We ran it fine for the last 2 days, but got on it today to ride and when we put it into gear it died. It starts and idles fine, but once we put into gear it dies everytime. Any suggestions? It seems to have battery power and all the lights and stuff are working fine, it just clicks and dies when put into first gear. Thanks.
A . It sounds very much like your side stand is down - or at least the side stand switch thinks that it's down. Most bikes are wired that way these days for safety (saves a nasty accident on the first left hand corner...). Try removing the switch and giving it a good clean, check the wiring around that area as well - a wire could have broken off or something like that. Worth a try eh? (Nick Lappage) A . My 1995 XV535 did exactly the same thing. In the end the problem was with the clutch plates being almost glued together. Once they were freed and cleaned, problem solved. Hope this helps. (Damien)
Q . I have an 02 Dragstar 650 Classic, and today after slowing down whilst leaving the motorway the little darling cut out. Anybody know why or has experienced this problem? A . Hi, I have also had this problem, every so often the engine just dies, usually when in the fast lane, very frustrating and also lethal. After much swearing I returned my Dragstar to the shop, and it turned out that some water had got into the sidestand switch, shorting it out and telling the bike that the side stand is down therefore cutting the power. All they did was disassemble the switch ,dry it out and pack it with grease, and since then I have had no problem. I hope this helps you. Andy Smith Q . My 650 Dragstar developed a knocking noise on further investigation I found the three rivets that secure the clutch basket had started to break up. Has any one else had this problem???????
A
. Have just had the same problem with mine - and only found bits of one rivet head! (attached to magnetic drain plug I fitted about a year ago). Also found the clutch 'basket' was notched up the edges - and my bike although a '97 model has barely done 8000 KM!! Gear change was really noisy. Am about to replace the offending parts and hope no more metal is loafing about in the engine. Any comments or insights would be more than welcome. Is this a manufacturing defect and can I claim from Yamaha despite the age of the bike?
Q . Has anyone heard of Implosion of Dragstar 650 petrol tank as mine has had this happen. Any suggestions as to where I could get it repaired or replaced or maybe even self repaired? A . Yes, I've seen this happen to a friend of mine. There is a vent tube at the front of the fuel tank which has a rubber hose coming from it and routed under the fuel tank. It has been known for this hose to be kinked (e.g. when the fuel tank has been removed and then replaced for service work etc). Then, when the petrol is sucked out of the tank by the fuel pump an internal vacuum builds up. This is normally noticed as a hiss when the petrol cap is taken off. Sometimes the vacuum pressure is so great that the tank will implode. A good preventative cure is to get a replacement petrol cap that has its own ventilation. (Nick) A . Hi, I have just had this happen on my wildstar. The problem was not the rubber hose but a blockage in the metal vent pipe that the hose attaches to on the tank. Resolved by forcing air down the pipe with a decent power air line. Apparently a common problem as the vent hole is so small that small particles of the dreaded rust from in the tank will block it. A must not do is to try and clear it with a piece of wire. Regards, Steady Q . I have a 535 and want to fit a set of 10” rise square bars. Does anyone know if they’ll fit without having to change all the cables? A . Hi DB, I recently fitted 4" risers to my 2002 535, cables etc are on the limit. The maximun safe height risers without modification would be 3". (From Robot)
Q
. I need to adjust the valves on a 1988 virago. How do I do this?
Q
. I have a Virago 535 and have had it for 2 years. It is a '92 model and has done 21000 miles. When it gets warm it has a top end rattle that increases when I rev it or accelerate. I have checked the tappets and all are okay. Advice on what it could be would be appreciated.
A . My 1100 was the same and when I put it in for service the fitter set the tappets to what Haynes say they should be and it was not much better so he phoned Yamaha and they gave him different settings and now its sweet. Arthur Q . Hi. I own a 650 Dragstar 02 reg 10,000 on the clock. I purchased the bike new and find that at 65mph it develops a rough vibrating ride. Up to that it's smooth. But now, from 65mph onwards, the bike seems to feel rough and vibrates all over. Is this how they all are or do I need to buy a bigger bike? Andy (Centre 13) A . I bought mine new last September and its just the same, anything over 60mph and you can feel the vibration through the footrests and the seat. Phil A . Hi there. Just thought I'd chuck in my penny worth. I have just sold my 650 and moved on up to an 1100 "BUT" I bought my 650 new, it's a 1999 bike and has 19500mls on it and I have never experienced any vibration. It has non std pipes and has been Dyno jetted with a K&N air filter fitted and I must say it has always gone very well. Ride safe, Stu. A . I have found that from around 60mph to about 70 it gets a bit rough but after this smooths out but is mainly when accelerating hard (I know it's a cruiser honest) I am running a hypercharger, v&h cruzers and 122.5 main jets and 35 pilot jets performance is incredible (around 4.5 to 60 and two up cruising at 80 ) but balancing the carbs with a flow meter made it much smoother but has not got rid of the vibes completely as this is a trait of v-twins. (Rob Jones)
A
. Hi Andrew, I have just assisted a mate of mine with the same problem with his Dragstar. His bike was the same at around 70mph but then got worse. In the end it lost all power. Mileage done around 18k. We got the engine stripped and found a bent con rod for the front cylinder and excessive wear on the crank shaft.
A
. 1. They can clock a lot more than that usually.. they're based on the old XV535. There is a train of thought that with the odd few, and it really is the odd few, a lack of oil changes can be a problem. This is cos the filters are a bit of a sod to change without stripping the bolts in the cases that hold the covers on. Aside from that, it's not known to be a problem.
Q . The speedo on my '93 XV535 tells me I'm travelling at 65 when I've been told I'm doing about 75mph. there seems to be an error all the way through and at 75mph I am really travelling at about 90mph (whoops). Does anyone know why it might be doing this and have any solutions without buying a whole new speedo? Any replies to annie@burrowsannie.fsnet.co.uk and the webmaster One of the long bolts, which hold the oil filter cover on,
had stripped the threads in the engine block. I couldn't get the bolt to tighten and
had a minor oil leak/weep. After asking on the Wanted pages, please post my thanks to all the VSOC members who responded to my oil leak problem. The advice was that even though the threads seemed stripped, there would be another 5mm of thread in the casing. Indeed there was so, after finding and carefully fitting longer bolts, the problem has been solved. _________________
If anyone is interested, it is a very easy change to put the later, chromed side stand onto a pre-1994 VX535 virago. The advantages are improved appearance, and much better stability when parked!! The original item left the bike a bit too near to upright, so a strong gust of wind could (and did) push the bike over.

If you have headlight problems on your Virago XV750
I have an 85 Virago XV750 and had sporadic problems with Tach/speedo/headlights going out. Tested every wire and relay in the Headlight and instrument cluster. Many thanks to the solution provided by the owner of the 93 with the same problem. His post info saved at least 5 more hrs of work by 2 people as we were ready to gut and test the entire electrical system. Same problem, solution and result! __________________
I have installed a relay which cuts off the front headlight when ever the side stand is down. This helps cut down battery drain during starting and also while sitting on stand during warm up. I can provide details if required.
Just a thought. I went and bought a set of chrome side panels, (never had trouble with the originals). The new ones seemed to fit ok, but first blast up the road, the right side came off with sods law making sure the car behind ran it over. It might pay anyone who buys them to drill a small hole and attach a cable tie so that if they do go, they don't get squashed!
Q . I was wondering if any body could help me. I have a Dragstar 650 bought new last September. When the bike has cooled down, there is a bad smell of petrol fumes, on my first service I mentioned this. The mechanic agreed there was a smell of petrol but couldn't find where it was coming from. At first I thought maybe it was coming from the petrol cap because it smelt of petrol through the keyhole, does the cap breath through the keyhole. Any ideas please? A . I have an XVS 650 2004 model and I have always smelt a bad fuel smell as well. No evident leaks either.
A
. Dear Phil, Just reading through the problem page and arrived at your problem about the fuel smell. There is a breather under the tank and this vents under the tank so any petrol vapour will filter into the closed spaces, under the speedo perhaps. When you have been for a run the heat rising from the engine will warm the tank making the petrol produce more vapour, hence the smell. I bet you only notice the smell on a still day (no wind), it is a sure sign that the tank is being vented correctly, be more worried if you cant smell anything, I had that problem on another bike and it caused no end of trouble.
Q
. I've got a Royal Star with a seat that seems to make me slide down towards tank and the riding position hurts my back which is not in the best of health. Any help would be much appreciated. Thanks Arnie
Q
. I have just recently purchased a Dragstar XVS650 Classic. I find the ride very hard and when I have a passenger, (I weigh about 14 stone and my wife is approx 8/9 stone). Is there an adjustment that could be made to the suspension to make the ride softer?. If so could you let me know what to do?
If, like myself, anybody is searching for a more comfortable pillion pad on the 650 Dragstar (not the classic) Yamaha will supply one: part no. STIR-4YV25-30-02. when mine came it was a Corbin seat. Cost is anything from £145 to £175, my wife said it was worth a lot more. (The Hawksworth family)
Q
. I have a set of Highway Hawks on my 650 DS I also have a burnt leg from the pipe from the rear cylinder. Is there a heat shield available anywhere to cover this. I cannot be the only one who has suffered this HELP !!
Q
. I have a 535 Virago. Bought it 2 years ago, and fitted (new) matching Continental tyres. The handling is perfect. I've covered 6000 miles. The rear tyre has 4 to 5mm of tread left. The front tyre has 2mm of tread left. I've has dozens of bikes, and the rear tyre always wears out more quickly than the front.
Do 535 Virago's wear out their front tyre more quickly than the back? If so: Why?
Or is there something wrong with my bike?
Q
. I need to renew the front tyre on my 535 Virago, but some tyre fitters are recommending that I fit tyres from the same manufacturer to the bike. Is this correct? I know that with car tyres you are not supposed to mix tyres of differing construction methods, ie crossply with radial. Currently, the back tyre has lotsa treat left, made by IRC, with markings Grand High Speed, 140/90 -15 70 S. The front tyre is a Bridgestone 3.00S19 49S. Looking forward to your replies.
Q
. Regarding Bravado Tyre Trims, I have tried to fit these to my tyres on my Royal Star but to no avail, they just keep blowing off the rims, has anybody out there come across the same problem and how did they rectify it?
I've cleaned the wheel & tyres so there is no contamination on them but to me the trims are made just that bit to big to centralized on tyre & rim to give a airtight seal.
A . Hi, I've just ordered a set of whitewall tyres for my XVS650 Classic from www.mandp.co.uk They sell MAXXIS Classic Tyres. Hope this helps. Regards, Mike Biggles. A . Conti' supply them (slim and wide) for cruisers. See www.conti-tyres.co.uk/contibike/tyres/milestone.php
A
. You had a question about fitting different branded tyres to your bike. I'm no expert, but went through the same queries a short time ago. The answer has to be 'it's recommended'. To get on a Type Approval list, the tyre manufacturer has to prove (by real, live tests, in wet conditions, at high speed etc) that their tyre is compatible with the bike. By buying the same branded tyres, you know they will be ok. If you fit different brands, and the bike weaves at 50 mph, what will you do? I have own a 2001 XVS1100 Dragstar since August 2004 which then had 2000 miles on the clock , just after 3 months from purchase with a further 1000 or 2000 miles on the clock it started to develop the a oil level light problem. After about 10 mins of setting of on a journey the oil light would come on and stay on for about 10/15 mins. Eventually over the next couple on months and a further 1000 miles or so the oil light permanently stayed on after a few seconds from starting the engine. By the way the oil level is correct and i have even tried it over full .
A
.
Hi yer. They all do that! No they really do! Mine did, Sarah's does, Anne's does, Ian's did etc etc it's a design fault with the oil level sender thing that Yamaha ignores exists! I used to just check my oil level regularly and ignore the red light. A little disconcerting but if you are confident in your engine and oil level its no real hassle to ignore it! Oil Level Warning Light Update Probably a lot of people know this but maybe some don't. On my 1988 XV1000, the oil light kept coming on when given a bit of throttle at about 4000 revs. Also on the side stand, with the engine running, it did the same. My thoughts were 'knackered engine = no oil pressure'. I found out through the web that it is an oil level light, not oil pressure light and it is a common problem to get a false low level warning. Thanks to Rovpaul@aol.com Q . I own a 1986 XV700 Import. After riding out with Virago owners, I have realised my bike is undergeared (60mph=4000rpm, 75mph=5500rpm). I would like to hear from other XV700 owners as to whether this is normal or has something on my bike been changed. The diff would be the obvious answer, if so will a diff from a 750/1100 Virago fit?
A
.
I have an '83 XV750. It runs 4000 RPM at 60 mph. This is normal for older v-twins. An 1100 runs about 3300 RPM at 60 mph. There's a good discussion on this in the forum at voc.org.
Rear Shocks and Suspension Problems Q . My problem is this, after 21 months and 15500 miles from new, I'm now on rear shock no 4. Yamaha, after much badgering, say that they THINK the load capacity is 200kg. They won't do, or even advise on, heavy duty shocks. Has anybody had the same problem? The beastie in question is a XV1100 Dragstar.
Update 1:
It is now 24 months at 17000 miles, shock no5 is beginning to fail! Yamaha's response is that I must be overloading the bike. I've heard from 2 people who have had similar problems. How many riders are having suspension troubles?
Q . Virago shocks are the pits!! I replaced mine with Fornales air shocks, no spring, so no bottoming out! They will fit any 1000 or 1100 Virago and they have polished (chrome like) enclosure. Rob
Q
.
XV1100 Fork Seals. I have paid for these to be replaced (leaking) to often now. I'm told that it's because the machine is not used enough. I normally do about 2000 miles year when the sun is out, then it goes back into the garage
A . Know this was posted a while back but having suffered leaking seals on the wife's new XV750 trike think it is because when parked for a while with steering lock on it puts pressure sideways on seal over time it distorts the seal causing it to leak all the time now park the trike in garage with steering straight no side loads this may help if parked for long periods.

Q
. I have a 1992 XV 750. The previous owner removed the left cover to replace the starter clutch and pinched the wires replacing the cover. I removed the case and repaired the wires and it started right up. Now before I complete the assembly the starter will not turn over. There is no fire at the solenoid I can jump around it and it will turn over but with no spark to the plug. I have
checked all the relays and the diode and all checks out fine. Does any one have any
suggestion on what it may be. Thanks for any help. Larry
Q
. I have a 1997 Virago XV750. Recently broke down a found that new battery was completely dead. Recharged the battery and started the tests with the bike running at 2000 rpm and noticed there was smoke coming of the rectifier on the back of the rear foot rest. I checked the resistance of the 3 white wires coming from the generator (stator) and all measured 1.4 instead of 0.5. Would this fry the rectifier? should I put on a new stator or do you know of a fix? Cheers Mick
Q
. Hi, I have a 1996 250 Virago, it will run for a few mins but when it warms up it blows the main fuse, I replaced the rectifier/regulator unit, the one with the heat shrink on it, but the problem remains, if I replace the fuse it will blow again straight away, but if I leave for a while it will start again, I'm running out of fuses!!! Any ideas? Thanks, Colm.
Q . Hi, I have a 1994 750 Virago, runs fine, running lights work, hi/low beam works ok, don't have horn, turning lights, or brake lights. Any suggestions on where to start to look for problems? Thanks, Ronnie Foster A I am restoring a 1982 XV750 Virago and had a similar problem. Pull the left horn and blinker apart. Inside there a small breakdown sometimes occurs. Its really tight but proceed carefully looking for broken wires. If wiring breaks down there it can interfere with the brake lights. Also if you don't have a wiring diagram. I would suggest getting one. I found one on the virago owners website.
Q
Can any one help me
I have 1983 750 virago with no spark at plugs I have only had it 3 months so new to Viragos Thanks Q
Hi. I’ve been working on a 535 for a mate who hasn’t a lot of cash. The bike has been stood for two years and after charging the battery and changing the plugs, I finally got it to run. However, my
Optimate said the battery was weak so I fitted a new one. Since then the bike start button does precisely nothing. I can’t hear the fuel pump either. It’s like there’s a cut-out switch or fuse somewhere. I’ve tried the clutch and sidestand switch and nothing changes. I’ve also clicked the engine stop switch, and I can hear a solenoid click but that’s all. If I short across the big terminals on the starter relay/solenoid the starter turns and the engine starts quite easily so I’m tempted to think this is what’s broken. However, as I can’t hear the fuel pump running, it seems odd and I don’t want to buy one and find I’ve missed a fuse or something. HELP! Thanks. Lee
Tip
My 1991 XV1100 Virago had been giving the odd misfire when idling but was otherwise running OK until I decided to replace the front exhaust and remove the swing-arm for painting. A lot of stuff was stripped off the bike to do these jobs and on re-assembling I was surprised when it wouldn’t start. I had fuel to the engine but no spark. After 3 days of frustration, checking and doubling checking I found the grey wire from the pickup coil to the igniter box had broken inside the wire about 2 inches back from the igniter box plug. This was where it bent back upwards to enter the wiring harness and being a sharp bend with general vibration had work hardened then snapped but because it was held together by the outer sheath had remained in contact until the movement from my dismantling. If it happened on mine there may be others out there with this problem waiting to catch them out.

Hi all, I felt the need to share this with all Wildstar riders as it confused the hell out of me! My bike - Wildstar, 4 years old with 31,000 miles on the clock.
__________________________ This info applies to the 535, but I suspect applies to most models. The problem was that the ignition switch became unreliable, and would not switch on every time. Sometimes it was found that turning the key on, and then turning it back slightly towards off would work. Then it failed altogether, in the dark on a busy intersection. Proceed as follows.
Q . I am really struggling with my charging system on my 1100 Virago. I have a new battery and a new rectifier regulator and the volts AC across the coils of the stator coils are about 20v at 2000 rpm. I have checked the earth of the rectifier regulator and all is OK - the fuse is not blown and the feed to the battery - red lead is OK - continuity to the battery - but only reads 3v DC out of the rectifier regulator.

Hi! In checking the Clymer manual I have just bought the engine number you list is for a U.S. model XV535A, 1990. If you ever need a manual, I highly recommend this one. Loads of info. Hope I've helped you out (Doug Townley)
Q
. I have a 1990 XV1100. Having laid the bike up for a month I tried to start it last weekend with no luck. I have found I have no feed to the fuel pump. Has anyone else come across this problem? I've been told to check the relay but I'm not sure. Can anyone help please?
Q . Bike starts if left long enough but engine only runs for 3 or 4 mins then dies. As it dies the fuel pump relay makes fast clicking noise, don't know if this is normal. Fuel pumps as far as the carbs continuously. Doesn't run on one cylinder, both cylinders die. Have put in new fuel pump relay to no effect. Was using a lot of Redex in fuel 'cause thought it might be carb icing but bike doesn't start unless left overnight. Any ideas please? A . Hello. I have an 84 virago 1000 I have similar problems with my bike. I did a complete tear down and rebuild of the bike and before I took it apart it had a slow clicking to the fuel pump and when I put it back together it had the fast clicking that you are talking about and it did the same thing yours does, starts, runs for short period of time and then dies. As soon as it dies the fuel pumps starts clicking again real fast. Now I know I have tried everything I could think of and I could not figure it out. So I started talking to my brother and told him what it was doing and he told me about a car that they had worked on that ran real bad but they could get it started and then it would die and they came to the conclusion that they had the firing order out of wack. Well it got me to thinking that I did have the wires that go to the coils off when I rebuilt and when I put them back together did I cross these somehow. I started wondering if somehow this would be my problem. Well I read thru the book and there are two red and white wires that goes to the coils, one which goes to the left coil and one goes to the right coil, which I would assume are the power wires. Then there is a grey wire that runs from the igniter unit to one coil and an orange wire which runs from the fuel control unit to the other coil. Apparently it does matter if these two wires are backwards. Only the orange and grey ones would be backwards if they are. Again one goes to the left and one goes to the right. Well I looked in the Clymer manual and I had these wires backwards as far as I could tell. I switched them and I got the slow clicking in the fuel pump that I remember. Now I don't know if you had these wires off on yours but this seemed to be my problem. I just figured this out but I haven't got to ride the bike yet so I'm not sure if this fixed it but it seems to have done. P.S. the only wires I switched were the orange and grey wires right at the back of the coils . Jon Pridemore. Q . My 1990 H reg Yamaha Virago 1100 has stood for a while and now won't start. Starter motor and solenoid gets hot and drains battery. Any ideas please?

. Although electrical problems are usually hard to pinpoint, I would guess that your problem sounds like a bad ground. I would check the ground wire coming off the battery for corrosion. Check it not only at the battery but also at the frame. Sometimes the wires will get corroded inside the insulation also but will look just fine on the outside. You can check this by bypassing the ground by just using some jumper-cables. Connect one end to your battery ground and the other end to a paint free area on the frame. If that does not work, you might check your starter gearing, if it sat for a long time and say water got in there, the gears may be locked up. Just take them apart, noting how they are placed in the case, and clean them. I would recommend getting the manual for your bike first however, because you don't want to play guessing games with how parts go back together.
Q
. My brother recently bought my 1100 Virago off me. It's been stood in his shed while he's been in hospital but now he can't start it. He's tried a new battery, tested the starter, checked the fuses, then he was told to get the relays tested, or it could be the Ignitor box. Any help would be gratefully appreciated. Alan
Q . My bike won't start....I have a 1984 xv1000. I was recently vandalized, they took the ignition, the part you put the key in. When they did that, they cut the wires to get it out. I got a new part, and replaced it. The bike won't start. The battery is good, and I don't know what else is wrong. I am thinking however that there is a fuse blown. The problem is I don't know where the fuse block is. The only fuses I found are in the instrument panel area. Are there more fuses? Why won't my bike start? A . I had the same problem with my 1985 xv1000 and there is a 20amp fuse under the seat. Hope this helps.
Q
. I am looking for advice for a technical problem I have with my 1980 XV 750. It will not start and I believe the idler gear will not engage with the starter ring gear on the crank! I have replaced the idler gear once already and this cured the problem for about a month only. I understand there is a technical cure - the original set up won't do it.
A
. Starter problems on the early bikes (mine's a 1982) are common. The friction clip on the outer idler pinion looses its grip. I put a jubilee clip on it and tightened it until it moved at 5.5 lbs on a spring balance. Works perfect. Then I found a place on eBay,
*chopperbobs*cycleworks* in America, who supply a laser cut clip that also does the job. They can also supply a 2mm washer to go behind the pinion to reduce how far it has to travel and stronger bolts for the starter and a shim. I bought the lot $38.40 USD and you also get a full parts list and items on the starter problem.
I also cut the spring down to about half its size, carefully bent the ends so it does not
foul up or snag, usually fires first time.
Q . Hi. We have a US import 920 XV & are having problems with starting the bugger! Despite having the starter rewound and fitting new brushes, it seems to suffer from a lack of 'effort'. The rest of the electrical system is up to scratch and a new battery is in place. Some years ago, a friend with an XV750 had similar problems and I seem to recall a modification or a different starter motor cured his problems. Do you have any info/ideas/advice or contacts who might be able to help us solve this ? Tools and facilities are not a problem - but the lack of knowledge is! Any help would be greatly appreciated A . If yours is a 2 brush starter motor you might benefit from a 4 brush starter as it works on my xv750.

Q
. My XV1100 has developed problems starting when hot. I've been told it could be the windings. Anybody know of anywhere I can get my starter serviced. Or can anybody give me any other advice of what it might be, I've already bought a new battery and checked the brushes. (Tony Centre 10)
Q
. I have a XV750 1992/93 model.. I was having trouble getting it to start on the button. I have replaced the starter clutch, checked and cleaned the starting motor, replaced the gear idler 2 (27t), replaced the wheel starter, and compression spring and it still wont start on the button.. It appears that the drive lever assembly is not pulling the idler gear far enough to engage with the alternator rotor cog on every attempt. If I put a screwdriver behind the drive lever to assist in pulling the drive lever assembly out some times it will engage other times it feels solid and will not pull..
Q . Hi All. Thought I had a flat battery when it wouldn't start- the starter just clicked away merrily without turning the engine. Bought new battery and guess what still the same problem press starter and the rapid clicking but no engine turning. Any ideas please? Cheers, Mike. A . Well the answer in the end was that the earth strap which is apparently behind the exhaust was loose!
Q
, I have a 1986 Yamaha Virago 1100 XVS bike and I get about 60 mpg ( Imperial so it is fairly economical ).
Q
, I have just put straight through exhaust pipes on my XV 535 DX Virago 2001. Do you know what size jets I will need as the engine is now running too rich?
Useful
Information. From time to time I visit your site, and thought I might have something to offer you in the way of carby help. I am a Virago Owners Club member from the USA.
After several years of working with European customers I though it worth the time to send you my link in case any of you chaps could use some help. My site and it's enclosed link will help explain much of what I do, but if you have any questions please feel free to ask. 1) Just like to share a problem that hopefully I have now resolved. 2) As I know you get more than your fair share of carburetor-related questions I thought I'd add my 2 cents to your bank of information. If you ever find that any of your subscribers need extensive and thorough carburetor work, please feel free to consider offering my services as an option.
Q
, I have a set of Highway Hawk slash cut pipes on my `96` XV1100. I have removed the baffles and
I want to know what size main jets to use in the carbs. Is there a rule of thumb size for an unrestricted
exhaust.
Q
, I've stripped my '91 XV535 down for refurbishment, and noted that in the carb intakes there are metal washers with an offset hole. I assume they are for restricting the bike. Does anyone know if it's ok to fit the intakes without the washers, and if so, what else would need doing? e.g. jetting changes etc. I'm ok with stripping and rebuilding the bike. apart from the engine (duh!). Everything else I can manage. Any help gratefully received.
Q , Hi, I hope someone out there can help. I am new to all this, I bought my first big bike a few months ago (Virago 535 1997), the dealer told me that I should expect well over 100 miles on a tank of petrol. I do not over rev or go stupid on it but I can only ever get 90 miles before I have to switch to the reserve, is this normal ? I am not bothered about the cost in petrol, I do not want to damage the bike, if there is a problem then I want to get it sorted. I hope someone can give me some advice. A , I get about the same out of my bike, and it is the 'two tank' style. If you've only one tank it'll be less. Doesn't seem to matter how hard you ride either - I still fill up about the 90 mile mark. I don't use reserve very long at all, but it should be good for about another 15 miles or so before you're pushing... (from Andy Palmer) A , I have a 2002 535 and fill up around 110 miles and have never put more than 8 litres in (13.5 ltr fuel tank). From cold I turn the choke off after a mile or so. In your position I think I'd have the bike serviced and get them to check the carb settings. (from Robot) Q , 1998 535dx when throttle just opened engine revs increase until engine races. Engine sounds like it has a slight miss, starts no problem and ticks over quite smooth. I have never had to use the choke to start the bike. The diaphragms look ok but one seems a lot less pliable than the other. Any help greatly appreciated. Also does anyone know where to buy reasonably priced spares, I have been quote £53-00 for one diaphragm. A , When my diaphragms went it paid me to phone up Partfinder (09060 300 100, £1 per minute for about 2 minutes) and order a whole Carb. The carb was virtually brand new for £50. You are right that the dealers will charge near that amount for just one diaphragm. Wouldn't be so bad if they were reliable. One tip for you - try and run the bike as often as you can with good fuel, especially in the winter, the diaphragms crack if they're not used. (from Andy Palmer)
Q
, Confusing Engine Troubles.
A
, This is a good 'un and one of my C19 buddies had a problem just like this fairly recently. Turned out that the low tension feed to one of the coils was hanging on by just a couple of strands. The effect was to limit the amount of current available to the coil, hence under certain load conditions the bike would either "hang back" or run on 1 1/2 pots. Also, look for any evidence of damage to the wiring harness. I had one detach from the frame and gently trail onto the rear pot exhaust header. This resulted in intermittent shorts in the ignition system and a lot of hassle.
PS.
Hi guys,
Q , I have a Virago 535. It just seems gutless. It only seems to pull to 55 mph and that's it. When I go down the gear box from 5th to, say, 3rd it wont give me any more. I've checked the carbs and they seem fine, plugs have just been replaced and the air filter too. I've run out of ideas can any one help?
A
, Did you check the condition of the carb diaphragms, not only for holes or tears but also for how well they fit to the slides? What you describe sounds like classic carb diaphragm failure to me. Does the bike run out of breath straight away, or does it run well from cold but get progressively worse as it warms up? If so, suspect the carb heaters. You must remove the caps from the carburettors that cover the diaphragms. Then withdraw the diaphragms and the carb slides. The diaphragms must have no holes or tears in them. They must also be a tight fit on the slides. If they are loose or damaged, air will leak past them and give precisely the symptoms you describe.
Q .Why does my Virago 535 have a loss of full throttle power?
A
. My personal experience of running a 535 which suddenly lost all bite when opening throttle more than half, seemed like a breathing problem, so checked out filter, crankcase breather etc.
Re much-documented diaphragm problems. My '91 535 Virago recently started to perform really badly, not pulling, max speed 50 mph. I could not detect a mis-fire, it just wasn't pulling. The rear cylinder plug was VERY sooty, the front one was a bit sooty round the body, but the spark gap area was a nice light brown. The rear diaphragm assembly had simply come apart. The diaphragm is held on the black piston by a pressed metal collar. I simply superglued the collar back in and everything works. One point of caution: when you remove the piston and needle from the carb, check that there is a slight bit of play in the needle. i.e hold the piston in one hand and press the tip of the needle. There should be about 1/16th" of spring play in it. Hope this helps somebody one day
By way of a big thanks...
Just wanted to let you know, I have a '96 Virago. Last weekend I was having the same problems listed on your site under "Carb Problems"...my top end speed in 5th gear was 50, and it was backfiring and fouling out plugs. We found your site and my husband realised after reading some of the listings on your site that my carb diaphragms were in 3 pieces instead of all one piece. He glued them back together, and put them back on. We rode the rest of the day. We almost got caught out in a storm, but made it home 10 minutes before it hit. (had to ride 70-75 mph to make it home) Thank you all for sharing your experiences on here., sincerely, Brenda, Oklahoma USA
Had the usual diaphragm problem with the XV535...Checked and found that the rear carb diaphragm had small tears around the very edge...patched it with some Loctite Superflex sealant spread thinly and built up gradually...that was 2500 miles ago and still no sign of problem returning... (Nessi)

Q
, Greetings, I think I have the same problem with the solution described by Andy
Bond (below), please clarify this fix: what did he mean by "loose nuts at he rear swing arm bushes". This might be a life saver for me since i nearly had a mishap the other day when i tried to overtake
another vehicle, when i steered my bike it weaves in the other direction. More power to the Virago Star Owner club (UK). always ride safe
Q
, What a machine, it rides beautifully at speed, but I notice when I slow down to 40mph the bike starts a ‘weaving’ motion from side to side – it is not too drastic, but I wouldn’t want it getting any worse! I have checked tyre pressures which is the first answer most people give and I think that they are wearing evenly – the bike has done
approx 20,000 miles now – any ideas on what could be wrong?? Q , Following my advice, my mate has just bought an 1100 Virago, he tells me that it has a strange steering twitch when he accelerates or decelerates around the 60 mph mark. I've never heard of anyone else experiencing this and wondered if anyone could shed any light on the matter for him. He took the bike to Yamaha who could find nothing wrong. He's now talking of selling it and buying a completely different bike. Just as I was talking him into coming to the next Vultures meeting. Any advice gratefully received. Thanks, Colin Hawkins. A , I had the same problem on my 535, although I didn't think it was a problem at the time, as I thought that that was how the bike handled, and just got used to it. But when I had the MOT the tester failed it, and asked if I was having problems with straight line steering and an uneasy turning arch going round corners and bends. I said yes. He showed me that the rear swing arm bushes were loose, to me they didn't even move, but when he showed me the travel horizontally at the furthest point at the end point of the rear wheel it turn into about 1 1/2 inches, which was more than enough to cause the problem, the bush nuts were duly tightened, and bike rides like a dream now, and a life saver. From Andy Bond
A
, XV 1100 1996 3700 miles. Mine has started doing the same at about the same speed, if I open the throttle big time at about sixty mph the arse seems to want to over take me, and sometimes going into bends the bike will dip to much like you have a
puncture in the front tyre and drags you down (frightens the shit out of me), I have just spent £450 on a full service and two new tyres (London rip off bastards) and the problem is still around but not as bad. I have a service on my bike before every 4000 miles riding; all bearings and bits have been changed at Yamaha’s recommendations for service intervals. Now is it me or shall I
(except that I am turning into a old tart) get myself a 125 with L plates??
Q
, Has anyone measured how much fork oil goes into each fork on a (J)1992 Virago 1100. I know that the Haynes book of words states that it should be 179 mm (7.0 inches) below top of inner fork tube, but it would be a lot easier to pour the correct amount (mls or fl oz) into the top of the forks.
Q
.I have a Virago xv1100. I have a bug screen that has cracked from 2 off the fixing holes don't ask me how it's embarrassing. Is there any way to fix them or can anyone tell me where I can get a new
Perspex screen only. It was bought from Yamaha a long time back by the previous owner. Any help would be truly appreciated" Q .I have recently fitted a National Cycle Heavy Duty Touring screen to my 2001 model 650 Dragstar which fitted perfectly, however there is severe wind buffeting at any speeds over 45mph (at 60mph its so bad that I cant even focus on anything). I have tried adjusting the screen from its lowest to its highest positions, adjusted the rake of the screen and even tried several different crash helmets to see if that would help but all to no avail. When the screen is in its highest position it is well above my eye level but the buffeting is still there. Does everyone else with screens have the same problem or is it just me? If anyone has any solutions or has the same problem I would be grateful to hear from you. A . The problem with the wind buffeting on the Dragstar (V-Star here in the states) is the wind coming up from under the windshield and over the tank. The wind then hits you right in the chin and chest and bounces your head around. The way to test if this is in-fact happening is to fold an arm over your chest when going down the road. If the buffeting decreases or stops, then what is needed is lowers mounted just under the shield next to the forks. They deflect the wind out and around you when you are going down the road. It worked for me.
A
. Hi. I had the same problem with my Dragstar and the Yamaha screen. After a lot of messing around trying highest/ lowest and changing the rake of the screen I found that the rake allowed wasn't enough to pull the top edge of the screen back far enough to allow the wind to flow over the screen smoothly. I took a round file to the top holes in the brackets that attach to the forks and elongated them backwards towards the bike. This allowed me to set the screen back as far as its possible to go and this cured the problem. (note that if you do this you will need to leave a small, 2 to 3 mill, gap between the screen edge and the brake master cylinder to avoid marking the screen). Hope this helps. Regards, Steve
Q .I have a 535 Virago, when removing the nuts securing the exhaust pipe to the cylinder head, both sheared off due to rust. I now have 1/2 an inch of stud left sticking out of the cylinder head on both sides. Any suggestions on how to get these out so I can replace the studs? A .Grant. There are several ways to get broken studs off - stud extractor, drill and tap, etc - but the most effective way I have ever found is to place a nut over the stud (obviously slightly larger inside diameter than the stud itself) and weld it on with an electric arc welder. As well as giving you a nice hex head to put you spanner onto, the heat shock often releases the stud inside the head. (Hint: don’t use gas welding gear as the heat exposure is longer and it is almost certain to melt the alloy cylinder.) (Many thanks to Geoff Pflaumer)
Q
.I have a Virago XV1100 which seems to be fitted with a restrictor kit in the electrical box. I wish to have this removed but am unsure as to how to do this - it may cost me in the region of £200. Can anyone help me - or give me any suggestions?
Q .I have a 535 Virago which is limited down. We have checked the carbs and there also appears to be no limiter in the exhaust, any suggestion as to the removal of this limiter would be greatly appreciated. A . My XV535 has a restrictor kit fitted (F1 International) which is a thin metal plate fitted in the inlet tract between the carb and head. Some have just a hole (like a washer) to restrict the airflow while some others use a series of 'fingers' around the hole pointing in towards the centre. I think this idea is to help atomise the fuel as it passes to help prevent running rich and requiring a jetting change. Let me know how you make out. I still have to remove mine which will be real soon!!!! (Doug Townley) Q .Just bought a XV1100 Virago to replace my 535 which was stolen. I wanted to know if there is a cure for the incredibly stiff clutch lever on the big Virago compared to it's smaller sibling, or am I just going to have to build up some strength in my puny hands. Thanks for any help. A When I first purchased my 1100 I too thought that I was being whimpish and suffered the same clutch problem, it also had a tendency to slip when I was in a hurry, until.........don't you just love rallies........at the Gems I got to ride another and was amazed at how light it was. Taking the cable off immediately showed what the problem was, I could hardly move the inner. Liberal application of plus gas followed by WD40 has solved it. (Thanks to Alan Johnson)
Q
. Hi. Just bought a '95 XV750 fitted with Remus slash cuts. Anyone know how the baffles come out? Theres no holding screws/bolts etc... as it's a bit quiet.. thanks
Q
. Hi there, I'm thinking of putting an after-market exhaust system on my XV535. Has anyone done this and if so, can they tell me whether there are any increases in power or any weight-saving advantages. Also, if it's worth it, where can I get one from. thanks. Anne
Q . I am interested in fitting after market exhausts to my XV1100s. There are many products available from the Heine Gericke slip ons (really cheap) to the Highway hawk products. Are there any other products available and what carburetion modifications are required. Also, I want to boost the top end power of the bike to enable tome long distance cruising, France and Spain. Any Ideas? Any recommended tuners out there?
A
. I saw your query on after market pipes for your Virago. Living in Canada with the same bike I have a set of Vance and Hines Classics on my '95 Virago 1100. Great sound, very much like a classic Harley Davidson. You'll need to re-jet as well, which goes with out saying when you make your engine breath better. Attached are two pictures, one is of a Honda Shadow with the V&H Classics on it, the other is a picture of my bike the day I picked it up, (August of this year.) Check out the link to V&H's European site http://www.vheurope.com/ and I have also included a contact for a distributor in your neck of the woods.
Q . I wish to put Highway Hawk Dragon Pipes on my XV750 Virago (USA speck). Would I have to do any alterations to my carburetors or anything ?
This site might help: Scroll to the bottom Q .Can anybody help me? I recently required a 750 Virago which keeps burning the electrode of the plug on one cylinder (after 100 miles or so) causing it to misfire. I've had the coil replaced and the carb cleaned and nothing seems to cure it, but when a new plug is put in, it runs fine until another 100 miles. Help!!
A
.
Hi Ben, With a single carb (?), a blockage would affect both cylinders, so it sounds possible that the inlet valve for the cylinder in question is not allowing enough mixture through. i.e. running to lean which would cause the plug to burn out. Valve adjustment is a quick easy fix if this is the case. Hope this helps, regards, Steve
Q
. I have a 16 year old XV535. After cruising for a while upon deceleration the Engine just runs down in revs and stops. It will start again and runs fine ! Apart from that the engine seems to run fine. Anyone had this kind of problem? I am also trying to locate the mixture adjustment screws (Mikuni Carbs) These are not clearly shown in Haynes manual of course ! Would appreciate any advice. Q . Just like to share a problem that hopefully I have now resolved. Problem started with poor running and struggling to reach 55mph. Looking on your excellent website and other FAQ's realised that this problem with 535 Viragos was common. Did the usual, carb diaphragms no change, inlet rubbers no change, coil for rear cylinder as my local garage advised me it was only running on front at high revs and on demand, no change. Black Box sent for testing... returned okay. Garage had bike for a month and were scratching their heads and although they had the carbs off twice and told me they were operating okay suggested I buy replacements. Ran electrical continuity checks on all circuits and found that one of the carb heaters and the thermostat was not passing current. Isolated the circuit and took it for a run. 70 no problem and response and acceleration unbelievable in comparison to before. Strange thing is my 535 is a 1993 model and they were not fitted until 94 with heaters. Will get new parts when I can find a supplier (any suggestions greatly received). A
. Hiya. I had this problem (mine's an F Reg 89 model) - I was told Yamaha had
cured the problem later on with heated carbs but people with heated carbs still
report the problem. My local Garage said he was talking to someone in the pub
and they suggested fitting a hotter plug in the back cylinder. I was up for the
gamble and the bike runs real smooth now, is VERY responsive to a snap of the
throttle and just goes brilliantly. That was 2 years ago and I have not changed
the set up. It just works. A
.
Thanks for the response folks. Just thought I'd let you know the story to date. The chaps at Motorcycle Services in Derby suggested that I take my bike to "Sam's Dyno" in Hatton (
www.samsdyno.com
) for a diagnostic run so that they would have a better idea of what to do. The first thing Warren did was to check that the cylinders were developing pressure, because if they weren't then there's no point putting it on the dyno he said. The pistons are supposed to generate 145 units of pressure. The front cylinder was generating 155 and the rear was 135. He said that this could be due to the valves being too closed at the front and too open at the back. He also noted that my spark plugs were rated too hot for the bike and these two issues could be contributing to my problem. The run on the dyno showed that the engine was delivering power smoothly up through the rev's. Also the air/fuel ratio whilst OK, was running from slightly rich to slight weak going up through the revs. This he said was probably due to the after market exhaust. Re-jetting would probably help the bike's responsiveness at high power, but wouldn't help with my problem. Motorcycle Services have now adjusted the valves and down rated the plugs. So far the bike has been behaving itself. So hopefully I've got it cracked.
Q

Just purchased an 1100 virago from here not so long ago, but whoever it was left a few details out
Q
.
When I ride my Virago in the rain I lose power, it back fires and only fires on one cylinder. Took it to my local garage who checked it out but could not find anything wrong. Can anyone help? Thanks Les.
Q
.I have just bought a 1992 XV535 Virago. Everything's fine except when going down through the gears, say at traffic lights, and she wants to stall. If she does, she starts straight away again which, as you can imagine, is very irritating. Any ideas? Steve Rawlings (Basingstoke)
Q .I have a 97XV535 and since she got soaked a couple of months back she "chugs" at the slightest hint of damp weather. Starts off ok then accelerates and decelerates on a whim, I keep thinking I am going to end up in the back of a car. I have had the electrics cleaned and greased and the next step now is for new coils (so say the garage) but I am losing confidence in them because they can't seem to sort this out. I am also blowing lights at a fast rate. Also the fuel consumption seems to have rocketed lately, what should I be getting out of a tankfull? I ride my bike everyday and do about 500 miles a week, I am still very new at all this only having taken up riding in April on a 125 Intruder and then getting the Virago in October so any help would be appreciated
A
. XV 535's have some little flaws any of which can give you this type of problem.
1. Rough running & heavy fuel consumption If the bike starts ok but begins to run rough after a while on the road, suspect faulty carburettor heaters. XV535 carbs are prone to icing in cold and damp conditions - typically if the ambient air temperature dips much below about 12 deg C. The carb heaters are fitted to combat this problem. They can fail at any time during the summer and you'll be none the wiser. But come the cold weather you'll definitely notice that something is not right. The effect is rather similar to that observed when trying to run a hot engine with the choke on. From your description, I would suspect the heaters first. If the bike starts ok and runs well but inexplicably runs out off puff early in the rev range, or feels like it's top speed is restricted, suspect split or loose carburetor diaphragms. XV535's tend to suffer from this problem, though bikes that are used less often are generally more prone than those used frequently. Split or loose diaphragms hamper the operation of the carburetors resulting most usually in power loss, but can also cause rough running - especially if only one of the pair is affected. Poor charging, or a duff battery can result in the igniter unit not functioning correctly. This will also cause the bike to run rough. Which brings me on to ...... 2. Blowing bulbs. Check that the regulator/rectifier is working correctly. These are prone to failure on 535's. My fave mod is to fit a unit from a Honda - CBR600, Super Dream or CX500 are all suitable donors. This is a much sounder unit than the stock Yam item, once fitted it you will probably never see another failure again. The rectifiers used by Honda do vary a bit from bike to bike, year to year etc, but they can all be used reliably on any XV's. Typically, there will either be five or six wires. If the unit has five wires, there will be three the same colour - often either white or yellow - these are the phase connections to the alternator. The other two will be either red with black or red with green. In either case, the red wire is the positive feed to the battery and the black or green wire is ground (frame). This six wire rectifier differs only in that the extra connection for voltage sensing. In this case, the three alternator phases are the same as for the five wire unit. There will be a red wire which is a positive feed as before. The green wire is ground and connects to the negative battery terminal. The black wire is the voltage sensor and connects to anything that is positive once the ignition is switched on. The feed to the fuel pump is a handy place to make this connection. On a good battery, the voltage across the terminals should not exceed 14.5 volts with the engine running. Maximum alternator output is achieved at 5000 rpm, but you should see a steady rise from around 13.5 volts at tick over. A failed rectifier/regulator unit will either result in no charge at all, or the voltage rising to a very unhealthy 17 volts plus, without any control whatsoever. Note that bad earth connections can also result in bulb failure. So if you're seeing the same one blowing all the time, then suspect a dodgy connection. Hope this helps, Scoops.

.
My wife's Virago 535 had problems with running on one cylinder and when you placed your palm over the end of the tailpipe that was running rough it sucked instead of blowing! I read on the FAQ's page about diaphragms and HT leads!! The diaphragms when not used much go hard and don't operate as they should which causes the engine to run rough, so I rubbed Vaseline on both sides of the diaphragm which softened the rubber (Vaseline is a oil based lubricant) and I also used it to seal the carb cap to the diaphragm. Next I took off the HT cap and cut the HT lead down by 5mm as the core had less wires showing than it should. The bike now runs on two cylinders and acceleration is smoother with no back-fire as you build-up the rev's.....
Q Can you help ? I want to fit spotlights to my 2000 model XVS650 but want to keep the original indicators in the original position. Can you let me know who makes a light bar which would let me keep my indicators? Also do the lights get wired into the main beam/dip beam circuit or do they need a separate circuit , relays or switch etc.?
A . Hi, Yes they do make a light bar which holds the spots and keeps the indicators in the original place. I fitted one to my V STAR \ Dragstar 650 Classic. I run mine straight from the headlight but if I have them on for to long they do drain my battery, so I'm either going to put lower power bulbs in or put them through a relay. I don't know where you are but I bought my bar from Stateside Motorcycles in Bournemouth, Dorset but you can get them from lots of dealers. Hope this helps. Regards, Mike. Q . Question - I have exactly the same problem on my DragStar custom: my two extra spotlights drain the battery flat. Did the lower-power bulbs or the relay help? A . Well, I've put in 35W bulbs to replace the 55W bulbs that came with the spots, and I can tell you that a stock Dragstar battery cannot power stock headlight + two 35W Halogen spot bulbs. They still drain the battery flat. Time for some re-wiring, I guess...

The bike will run with spots without any issues if you get the output from the charging system tweaked up a volt or 2. To test whether this needs to be done, position the bike with headlight pointing at a wall or garage door. Start the bike, switch on headlamp and spots and rev the engine. If the lights go bright when you rev then dim when you don't (and there's nothing else wrong, battery etc.) then you need more from the charging system. Another test is to put a volt meter across the battery when the bike is running and the lights are on. You have to have more than 12 volts or obviously the battery will go flat. Hope this is of use, regards, Steve
Q
.I have a 1997 Virago 1100 and recently put on a set of forward controls, which are great, but the back brake is now next to useless not that it was brilliant before. I can only surmise that it is not as effective as it was due to the shortening of the brake arm with the forward controls. Any one got any ideas on a fix as I do not won’t to loose the forward controls. Terry.
Q
.Can anyone help me, I want to attach TC forward controls to my 535cc Virago, but I have a Yamaha engine bar and am unsure if I can fit forward controls and keep the engine bar on. I would appreciate advice.
Q
.Can anyone tell me if fitting forward controls to a 535 is a bit of a **** of a job? I've found a set of Mapam controls but am told that in order to fit them it's not simply a case of taking off the footpegs and bolting on the forwards. Any experience?
Q
.Can anyone help? Looking for more information regarding KJS Single Carb Manifold conversion kit for Virago engines and is there an alternative product made in the UK. Cheers in advance BADSY
Engine Clunks When Going into Gear Q . I own a Dragstar XVS 1100, only 4000 miles on the clock and a "T" reg bike. The bike is only a couple of months out of its two year warranty. The engine makes a clunking noise when it is put into gear and also when the engine is switched off. My local Yamaha dealers mechanic does not know what causes this noise and suggested that we let it develop. Last week I went for my first long run on this bike, from Fort William to Accrington. The mechanic at Clarke's of Accrington suspects the starter gears, I suspect that he is right because on day two of my long run I got as far as Sleaford near Lincoln when the starter motor shaft sheared. Do any other Dragstar owners have bikes that clunk when put into gear or when the engine is switched off or is mine a one off? Can anyone help me find a starter motor?

Hey there fellow VSOC'ers, GIBBO here from Centre 15.
Does your Dragstar or VStar 1100 have twisted starter bolts?
A . Regarding the question on "Engine Clunks When Going into Gear". This is as far as I know intentional - to make it sound like a Harley - my gearbox does this too, and so do all Dragstars I believe. (Morten Jorgensen) A . Hi, I have a Virago 535 which has always "clunked" when selecting first gear, particularly when cold. Regards. Henry. A . Mine does that too! Having met other owners, mine is W reg it seems to be a common fault. Have you sat along side a Harley when he engages first? Thanks to Graham Clayton for that one. Q . Hi my DragStar also clunks into first gear when first started or if stationary for a long period of time. It is not too bad when warmed up though. My bike also clunks through the gears on occasions is there a specific speed at which to change between the gears to avoid any clunking? Kev.Kiff612@mod.uk A . Hi there, Regarding noisy gear engagement on Virago models . I ride a 535 which has done nearly 50,000 miles .When you get your bike out the garage , especially if it has stood a few days , unstick the clutch . Sit on the bike , start pushing it backwards with your feet , then pull in the clutch and engage first gear . Bike gearboxes unlike car gearboxes have no synchromesh . So to change gear silently and smoothly , the two gears you are trying to engage need to be turning at the same speed . So , when changing up , if you change too slow , engine revs drop too much . You must close the throttle pull the clutch and operate the gear pedal virtually at the same time . The result is a silent sweet smooth gearchange . Changing down is similar , you must de- clutch ,rev the engine and operate the gear lever all at the same time . Only experience will teach you how much to rev the engine . On my high mileage Virago , I seldom hear a clunk as I change . Also check for excess free play in clutch cable . , I expect this also applies to Dragstar models . Hope this helps someone.
Any more answers anyone?
