Install Oil Pressure Gauge

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.

Question I have is how easy would it be to add an oil pressure gauge so I could see that the pump is actually working well and delivering sufficient pressure?

I have a friend who is mechanically inclined but I need a schematic that would help along with the right technical steps to do the job properly.

I notice that if I allow the bike to warm up I don’t get the oil level light flickering but it does flicker at the start if I take off with the bike cold. Also note that if the bike is running and I tip it too far to the right I can get the oil light to come on.

After being on the road for awhile and at higher rpm the oil level light has never come on during that time even on steep cornering. Seems odd that the light won’t come on while cornering but will if I just tip it to the right side etc. while stationary.

I check my oil level all the time and it is right up and the bike does not appear to be using oil with only 31,000 original KM on it. It was a great find. Love the bike.

Headlamp Fitting

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
Please email and the

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.

Wheels

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.
Please email and the

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. 
Alan Johnson (AJ) C14 Rep.

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
Email and the

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.

To remove the real wheel. Support the bike securely, unless you like lying down with it on top of you, detach the link from the brake panel and the brake rod and move them out of the way, remove the cotter pin from the axle nut and remove the nut and washer, loose the axle pinch bolt, support the wheel and remove the axle and washer, pull the wheel to the right, it will come honestly but it’s sometimes reluctant, remember to ensure the bike is secure, this should free it from the drive assembly. Reassembly is a straight reversal but carefully check and clean all components before reusing and ALWAYS use a new cotter pin. Torque for the axle nut is 105Nm.

Jetting Kits

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…
a) Would the 98 model year kit be okay to use?
b) Does this kind of thing cause any damage to the engine?
c) Are they easy to fit?
Any advice from anyone who has done this is much appreciated.

Bike Dimensions

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. Cheers Mick 
Email and the

A Hi. I have just measured the wife's 750 and it is as follows:
Rear indicators outside to outside - 21.5". Across handlebars - 30"
Footrests - I could not get a straight measurement but even going around the footrest hangers and bottom of the engine it only measured 28" so take an inch or two off.

Towing a Virago

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??
Email and the

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.

Rattling Viragos

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.
Please email
and the

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.
Cheers, Simon

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?
Thanks, Tony!

Petrol Taps

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 ?
Thanks, John Centre 13.

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:-

Remove the seats and clamp the rubber hoses from the top tank to the lower tank. Make a funnel which can reach under the manual tap and remove the 2 screws holding the front cover. Ease the tap to allow fuel to drain from the tap into your funnel and (hopefully) a bucket etc.

When the fuel has stopped, pull out the tap assembly completely, clean and replace the 'O' ring seal. Ease the tap assembly back into place and replace the 2 screw. Your leak should now be cured.

If you need to replace the electronic solenoid, the bottom tank will have to come out and Haynes shows how to do this.

(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.)

Restriction Kits

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.

I am basically looking for some information regarding restriction kits for the XV535.

To cut a long story short, we bought the bike from a dealer last year and had it serviced by another dealer earlier this year. Turns out that the frame is twisted...badly, and the bike is out of warranty so we have no backup from the original dealer...who'll no doubt say it was fine when he sold it etc, so we are in the process of fitting all the old parts on to a new frame.

The fact that we were sold a bike with a twisted frame, complete with MOT !!! has made me suspicious about whether or not they have fitted the restriction kit properly....wouldn't surprise me if they hadn't as the MOT was obviously not done properly.

So the crux of my question is, what does the kit actually consist of ??

Having removed the exhaust today, I can see that there is a large insert in the front downpipe to give it a smaller bore, but there isn't one in the rear downpipe.
I assumed both pipes would have been fitted with an insert so that they had the same bore, if only to balance the engine.
That said, the rear downpipe has a smaller bore than the front anyway, but a larger bore than that of the insert fitted in the front pipe......is this correct?

The section of down pipe from the rear cylinder, between the head and the collector box appears to be slightly cleaner/newer than the rest of the exhaust, which could just be coincidence, but i was wondering if the kit consisted of an insert for the front and a smaller bore section of pipe for the rear?

If this was the case I would have expected to have been given the section of old pipe when we bought the bike though, so it's probably coincidence that it appears newer/cleaner ?

We have a FIC restriction certificate and all that says on it is:
Restriction Device: Exhaust Restriction
Device Code 05-2YL-K25

Device Details And Dimensions
Outer Diameter 1 = To Fit Exhaust
Outer Diameter 2 = To Fit Exhaust
Inner Diameter = 16.5mm

And that's all it says. The way i read it, it seems to be suggesting that 2 exhaust inserts should have been fitted.

So to sum up, the front pipe has an insert and the rear doesn't. The front pipe has a larger standard bore than the rear, but the bore in the front is now smaller than that of the rear due to the insert being fitted.

Hope that all made sense. Please help if you can, any advice welcome. Thanks, Dave

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.
Regards, Susan (Dippydora - Centre 8)

Petrol In Sump

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?
Please email and the

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.
The fuel pump wasn't shutting off when the bike was tuned off, which meant when it was stood for a couple of days the sump would be full of petrol. This was discovered by attaching a tube with a stopper to the out bit of the pump and leaving the bike overnight, by the morning it was full of petrol. My pump has now been by passed and it has worked ok for the last year or so.
Hope this may help
Joanne

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)

Ran out of Fuel

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.
Please email and the

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? Thanks Sandra
Please email and the

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.
Hope this helps.

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!
I reckon this is one of the bad points of a 535.

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.

Now after 2 hours I was about to give up on it. It was just too narrow a gap underneath it to get my hand under & take the solenoid off that way leaving the tank in situ. After thinking about it I put the 2 top tank fixing screw back in without the thick rubber washers on & this pulled the tank up just a little higher enabling me to get a hand under it with a short Philips stub driver in a small ratchet to undo the solenoid. I managed to fit the new one the same way.

It seems that as long as you don't have hands like shovels it's possible to replace this item simply by disconnecting the wiring to it, take off the side cover & frame section, clamp the 2 fuel pipes, unscrew the 2 top tank holding screws & replace them without the rubber washers to draw the tank up 1/4" thus being able to get a hand under. Job done in a fraction of the time. It's just not necessary to half strip the bike down every time a job needs to be done as suggested in the manual.

Virago Engine & Drive Noise

 

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.
Please email and the

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.
A stuck starter solenoid is most obvious when you switch the engine off and it continues to turn over on the starter. A replacement solenoid is about £40.
Hope that this helps. Regards, Neil (Sting) Centre 8.

One Cylinder problems

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. 

Hope this helps. Regards - Andrew Gadd

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
Email any answers to Aaron McArthur on and the

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.
Regards Rob Jones (Centre 8).

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.
Any info if any one else has suffered this will be gratefully accepted.
Regards Rob Jones 5212 (Centre 8)

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.

Finally I hope to have this solved only a run to work will see. I have stripped down the fuelling system completely and have balanced the carbs yet again and have reset the fuel air ratio. We found that on a gas analysis that it was just over 1 when idling when it needed to be between 3 and 4. Have now adjusted this and sorry to all of you using Hyperchargers I forgot to count the number of turns on the mixture screw, but it is at least 4 times as much as listed in the instructions, the bike is now running smoother no flat spots and the over run sounds better not so much popping. Will keep you posted in case it reoccurs.
Ride safe Rob Centre 8

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.

Frustrated that everything I have done has not resolved the issue of the rough running and cutting out I rang my local dealer who proceeded to advise that the main culprit or culprits depending on which way you look at it was the COILS he carried on to tell me that on certain bikes not all (XVS 650/1100 and the Fazer and occasionally the R6) the most recent being a 6month old Fazer that the coils have an intermittent fault that causes them to go from 3ohm draw to a 5ohm+ draw causing the problem with the over heating and the coming to a stop as it throws the digital ignition out of sync which would explain why the timing was way out at tick over when recently retuning the bike as the ignition is working way to hard to spark.

I was advised that changing the coils would solve the problem I then asked if they could check them on their coil tester and the answer was NO we know the coils are a problem and if we get bikes with the syptoms you have described we do not test we just replace them the cost £116+ vat.

I have now ordered the aftermarket Items by DYNA £94 + vat for the coils and the DYNA 3000 ignition system to replace the possibly now spannered original as I have covered close to 1200 mile with the bike running rough/cutting out.

It is now sat waiting for the replacement parts as charging the battery will only allow 35miles of riding before going flat as the draw is much greater than the charging system can cope with, which is running at flat out at around 14.5.

( 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.

I have gone through every item of electrics, relays, wires and cleaned and greased all parts, I started at the back of the bike and worked forward and when I got to the reg/rec which on my bike has a custom cover over it (home made) which I though would protect it as it it's right in the firing line of the crud off the front wheel, only to find the connector fell to bits and was green and furry Argghhhh more expense was this the original culprit or is just another item to add to the list.

I hope fingers/toes everything crossed that this will finally solve the problem if not I think I will get rid and buy a different model may be a Wildstar, yes I think that's good idea! Now where have I left that copy of bike trader..?

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.

I now own a 05' Vstar 1100 (warranties and all that) as i cannot be without a star as they ride and look so good. Fitted with Baron slasher slip ons (no re jet req) and shaft cover Dealer is ok and will still warranty the bike with the pipes.

I was sorry to see the bike go but I had lost faith in it and a member of center 8 has nearly new bike Vstar 650 which is now starting to show the syptoms and the dealer cannot pin point the problem.

Is this the achilles heel of the 650? If it is, all the forums suggest a lack of maintenance blocking the oil galleries and causing starvation, due to the oil filter being a sod to replace due to the monkey metal casings. The previous owner to myself who we still drink with has finally admitted he never changed the oil in all the years he owned it (no maintenance), were as I religiously changed filter/plugs/ oil every 3.5K and as such had a relocator on order so as not to keep stripping threads. (got one on order for the 1100 even though the dealer will be sorting for two years and the interval is now 6K)

Knocks & Bumps

Q .

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.
Email any answers to and the

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...

Fitting Rev Counters

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.
Paul Barrett email and the

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. 

I fitted it partly to help diagnose bad running. It’s not 100%, as vibration or electrical noise means that the needle wobbles violently at around 6-7000rpm (this might be due to a duff voltage regulator, see below). Also I’ve never seen anyone quote a maximum rpm for this engine. It’s going to be between 8-9000 rpm. 

The cable was just long enough to reach into the right side pod where the ignition unit is mounted, and I fitted a water-proof plug, then wire tails soldered into the loom. Most connections can be picked up from the voltage regulator plug, but the illumination had to run from the instrument lights. 

Recently I have replaced the voltage regulator, too. The new Electrex RR48 unit does not fit where the original was, so I positioned it on top of the air-box (under the top fuel tank). There is just enough space, and the airflow feeding the engine should help to cool the regulator. After checking the clearance under the tank I drilled 2 holes in the top face, about 8-inches behind the air cleaner element (mind you don’t get swarf in the carbs, though!!). Then I put M6 bolts projecting up, secured them with plain nuts and lock washers, and fitted the regulator with more nuts and washers to suit. This means you don’t have to go into the air-box to remove the regulator, and the lower nuts space the regulator clear of the welded ridge along the spine of the air-box. 
Has anyone else found alternative locations?
Best regards, Joe

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!!
Any help to Baz at and the

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.
Ride safe, Steve

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

Wildstar Wiring Diagrams

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.

Virago vs Dragstar - Power

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)

Any replies to and  the

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.

With regards to upping the rev limiter you will need a DYNA 3000 (around £350), it also allows you to revise the ignition curves. I have fitted to mine, a Baron Custom Accessories BAK and jet kit, Baron's Nasty Boy slasher slip ons, Dyna 3000 set at curve 4 and rev limit set at 6750rpm and lowered 2" at the rear. It still looks like a cruiser but the performance, well let's just say the only way I'm going any quicker is to open the motor and fit HC pistons and aggressive cams which is another $1000 as I have to get it from S&S Customs or Pacific Coast Star in the States and then I will have a genuine 96hp at the rear wheel and great big bucket loads of torque - perfect for traffic light grand prix against anything this side of a tweaked 1000cc sports machine. So you can have both but as usual you got to pay for it. (Rob centre 8)

Hyperchargers

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

Top

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.

A few points on fitting: -
1) You can fit the jets without removing the carbs or the tank. Although to fit the Hypercharger you will need to remove the tank.
2) If you remove the airbox, be careful when refitting. The thing sits on a narrow collar on each carb. If you overtighten the clips the box will slip off the collar, and you might not notice. Running the bike like this plays havoc with the mixture . . . . I know.
3) The standard screws on the carb are bloody rubbish, difficult to get to and I can almost guarantee that the heads will end up mashed. I had to remove some with vice grips. I've now replaced the float chamber screws with slotted, pan head and the vacuum chamber covers with Stainless allen heads. This makes it easy to get to the screws which are 4mm threads with a variety of lengths.
4) I made the mistake of changing the needle settings. This messed the mixture up badly. The Kuryakyn instructions don't say to do this . . . . . Like I pay attention to anything :-) The settings are now back to how I found them, which was on slot 3 of 5. I recommend only to touch this as a last resort.
5) Set the mixture screws before fitting the Hypercharger
6) Expect to pull the whole thing apart a couple of times before getting it right

Here's what I did on my bike

The 122.5 main jet
The #35 Pilot jet
Straight pipes with severely chopped down baffles
The needle on slot 3
The mixture screws - screwed in fully, then 1 3/4 turns out

And lastly some useful links.

If you're a total novice, like me, the howstuffworks is short and concise on how carbs work. Worth a read.

http://auto.howstuffworks.com/

And, the thing that gave me the confidence to fit the Hypercharger myself.

Batteries

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????
Any replies to and  the

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: http://www.speedlinemoto.co.uk/SVR-WestCo-Batteries-mid-2-p-1.html

Noisy Starter Motor

I've just put a request on your site for a few electrical parts, and during my web search came across www.smallenginestarters.com who have xv starters - long and short shaft for about $160 US. Thought it might interest all 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
Please email and  the

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?
Any replies to and  the

 

A . So, Your Starter Is Just Clicking
Does you starter make a *click* sound when you try to start your vehicle?

Each time you turn the ignition switch to start, does the starter just *click* one time?

That is probably the starter solenoid.

If it goes, *click-click-click-click*, and so on, it may just be a low or weak battery.

The voltage test without any load, may indicate the battery is fine, but when you put it under load, like starting, a bad cell (or two) may be the culprit, not allowing all the current (amps) available (upto 230!) to go through all the cells to reach the starter. To test for this, do a voltage check across the battery when you hit the starter....if it drops from say 12.2volts to 10volts, you've got a bad cell.....

go get yourself a new and high quality battery......Yuasa make the best high cranking current batteries.........and don't forget to make sure you are charging your battery ok....the voltage measured at the battery terminals should show your bench charger or bike alternator to be charging the battery at 13.2volts to 14.2volts max.

If the battery is getting a bit old, it may loose it's charge. to test this....charge it up, stop charging, measure the voltage at the battery posts and it should be between 12.2v - 13.2v. Leave it for 2 hours and read again...if it's dropped below 11.8 volts, it's on the way out.

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. I've heard there is a modification for this problem, does anyone know it please?--------cheers Mick.

Venture Star Trunk Cracks

Hi,

I reported to the VSOC stand at the NEC the Trunk kit modification Re service bulletin M2000-008 and the difficulty that the kit 4XY-TRUNK-CM_KT was not recognised by Yamaha UK. For those who have a bike within the effected chassis range you can get the parts as individual parts as follows:

1 x Damper 4XY-2847N-00 ( rear)
2 X Damper 4XY-2847R-00 (front)
1 X Plate 4XY-2846P-00
1 X Plate 4XY-2846R-00
1 X Rubber plate 4XY-2847T-00
1 X Rubber Plate 4XY-2849J-00

The metal and rubber plates are handed to fit the contours of the trunk base.

Hope this information is of use to any Venture owners that might be concerned regarding the security of the trunk mounting.

Regards
Mike Wickins VSOC 3089

(Previously...)

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
The link is... www.venturers.org/NextGenTech/V2tech.html

It seems as though Yamaha UK didn't take too much notice of the modification kit that the USA provided and fitted a new top box under warranty instead. If some of you do have problems with cracking on your trunks, the modification kit costs about £20 and can be got directly from the USA. The Yamaha USA bulletin number is M2000-008 and the part number of the kit is 4XY-TRUNK-CM-KT.

Go to www.venturers.org/NextGenTech/2ndGen/pages/Trunk_kit.html for more information.

Engine Cutting Out

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

Clutch Problems

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?

Imploding Fuel Tanks

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

Vibration

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.
The shell (insert) was worn through right through the brass coating to the base metal underneath. I don't know the extent of your knowledge so excuse me in advance if I'm talking about stuff you know in the following.
The 2 con rods share a space on the crankshaft of about 4-5 cm. on this crank shaft all the wear was to the half used by the front cylinder only.
I had a Dragstar engine in the garage (why is another story) that had also done about 18k. I stripped this one with the idea of giving my mate some of the bits he needed. You can guess where this is going eh ?.
This engine has exactly the same wear issues as the other in the same place on the same cylinder.
Q . Do Dragstar engines have a life span of 18k ? Has anyone else found anything similar ?

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.

2. Just a thought on this subject but the symptom of one cylinder wearing more then the other may be symptomatic of not synching the carbs properly and one cylinder working harder then the other.

3. Sounds like the bike did a lot of running below the 1150 rpm range, the idle was too low and not getting up to rpm throughout the gears to pump the oil. It sounds great at low rpm but a disaster for the engine.

After getting all the replies from the UK and "across the pond", I think that the most likely possible reasons are the valves not being adjusted as part of the service and keeping the revs to low. (As, purely in my opinion, you would on a cruiser.)
The first was pointed out by a guy from Portugal, the service centres over there didn't do it and I have no recollection of it being done here either to mine until I asked for it to be done.
The second came mainly from the states where it is regarded as a "high" reving bike. The thoughts are that if run at too low revs too often, (approx less than 1500rpm )the oil won't get round enough resulting in too much stress on the cylinder...I'm no expert and it sounds feasible.
All in all I don't think there will ever be a definitive answer to this, just lots of points to bear in mind for the future.

Speedo Inaccurate

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?

Tips and Hints

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.
Many thanks, Joe Hatt

Hi there. Just thought I would add to your list off found faults I have experienced with an XV1100 I have just restored.

Once all back together , started no probs. Took it out for a run to clear the cobwebs. After approx 5 miles it started to hesitate an then died! turned the key off, then on again, pressed the starter away it went allowing me to get home, but cut out again in my driveway. The bike had been standing for two years! so suspected the carbs or a fuel problem although I had given these a once over. Off the carbs came , new jets, float valves etc. cleaned the fuel lines, again, and flushed the tank. Cleared the tank breather, sorted!

All back together, so off I went again, fairly confident I had fixed the problem.

Wrong! This time I managed to go approx 25 miles before it started to hesitate and then died. Turned the key off and then on again, it started no probs.

I managed to get home after another couple of stops and starts just a bit pissed off!!

I then decided to look at the coils by checking the ohms readings again. I had done this once when the bike was stripped and they seemed within limits then. This time however , the rear coil reading had dropped, I had at last found the fault !

New coil now no probs, runs like a dream!

Hope this might save someone time and money , it doesn't take long to check the coils , I would have done that first if I had known!

Cheers, Karl Parker

If you have headlight problems on your Virago XV750

I recently had some electrical probs on my ‘93 XV750; the bike was running well, but the headlight and speedo/tach wouldn’t light up. After testing every wiring harness on the bike, I checked both handlebar switches. After determining that they were working well, I was about to give up when my hand brushed against the start switch... and the headlight and speedo-tach lit up again. After “playing” with the switch for a few minutes, I determined that it was indeed the culprit; it wasn’t returning all the way back sometimes after depressing it.

After taking it apart, cleaning the contacts a bit, spraying a mist of WD-40 in there, and putting it all back together, it works fine. Hopefully, this will save someone else the 2 hours of work and troubleshooting it took me.

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!

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!
Ride safe, Paul (Virago 1000)

Petrol Smell?

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.
I hope this explains it? Regards, Tim.

Comfort

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?
Thank you, Andrew

Any replies to and  the

A The adjustment to the rear shock is under the seat and easily accessible with the c spanner in the tool kit. Ensure tyres are at correct pressure, (they are sensitive) and try a couple of settings, I used to put mine on level 3 which suited me (somewhat on the chunky size) and occasional pillion. It's a matter of trying and seeing what suits. Good luck, Ian.

 

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.
