2007 Yamaha vstar 1300 14000 miles recently I've noticed a noise which sounds like high pitched chain noise. This seems to be getting worse. Only happens when engine is warmed up. Only when decelerating. When bike is stopped no noise. Dealer has no idea. Sounds like a loose chain if I had to guess.. Could this be primary or cam chain?

SOURCE: 1999 Yamaha Vstar 650 Custom ...makes clicking noise when trned

i use a jump box on mine most weekends when i wanna take it out, i hook the red to battery and black onto my exhaust and it fires right up no problem. is the clicking noise coming from the fuel pump behind the ignition? it should click for a few seconds then stop. if it stays on then you are not getting enough fuel outta the tank, change the fuel filter and if bike had been stored for winter get a good fuel system cleaner, additive type. if in USA get Berrymans B12, double dose get bike to run hopefully let it stand overnight and all should be fine. fingers crossed. if is is clicking from somewhere else like starter or a relay by the battery, check all the ground terminals you can find

SOURCE: Engine makes noise when it gets hot.

If the cam was adjusted at all, they may have miss-aligned TDC.

I doubt this, but this is something to put in your arsenal of argument against a poor service experience.

They should resolve this issue without claiming obvious solutions first.

They are not incorrect in that setting a carb lean will cause these issues. It may be beneficial to simply tweak the carb first and see if this helps. Reference the owners manual, or do your best to observe the color and smell of exhaust under throttle while adjusting the carb. Its important to make sure you do not lean this out to far, as you already may know.

FixYa's! Can we can a second opinon on this please?

First off did you buy it new? Second has it gone through its break in tune up yet?Did you do the re jeting? My guess is it was re jeted wrong & neeeds to be re jeted again or could also need more air(upgraded air kit) or a tfi or power comand fuel mod.My bike also poped untill I did the air & fuel upgrades & them upgrades will also give you a much needed house power needed for this rig.


Bring it to a shop & have it looked at.......


Good luck

its possible that its valve clearances, but try to isolate at what rpm range the strange sound appears at and when is sputters, the sputtering could be due to a clogged main jet in the carb and the high frequency sound ussually means worn main bearings, but I dont think that with 3000km that would be the problem, try to identify at what rpm you hear it and post again and hopefully i might be able to help

Testimonial: "alexande rocks!!!"

SOURCE: Bike was dead - I installed new battery and no change.

Dead how? Completely dead where nothing lights at all? Like the other person said, check main fuse. If lights are on but the bike won't start, the starter clicks but won't turn over, bad starter. But if all the lights light, the starter works and turns over the bike, but it won't start, the kill switch is still activated, or the side-stand switch could be bad or corroded and stuck in from the last time the side-stand was down. I'm hoping you haven't been trying to start the bike with the side-stand down.

Also if your battery is good it will read about 12.6 volts or so with a voltmeter. If you been trying to crank the bike for five minutes or so the battery can be to as low as 10 or 11 volts, or lower.

Hope this helps.
