RE: trans noise
It depends on where it's coming from and how much is "a lot". The valve trains on these bikes are pretty noisy. However, there shouldn't be any whine from the rear noticeable and the noise you do hear from the engine area should be relative to engine speed not road speed.

If you've just got the bike or it's been a while since the oil was changed I would change the oil to a synthetic like Shell Rotella T-6. It won't make a huge difference but my 650 does run a little quieter since I switched. Also, unless you know it's been done recently I would replace the oil in the rear end, too.

its coming from front of motor only when trans is engaged at 40-50 louder than exh. about65 cant hearit
alittle quieter after oil change i use castrol v twin 20/50

its not the transmission, its the AIS reed valve: block off the 3/8 hose on the back of the AIS a marble works well. then block the small hose to the carb a golf T will work go for a ride and let me how it sounds. i will tell you how to quiet it and still keep it functional.

what's the mileage? chain guides worn maybe or tension springs weak. trans is behind the eng so i doubt thats it. very difficult to diagnose the cause of chain noise without tearing it down some to inspect the gears& guides

How many miles on the bike? I can't think of any gear/gear contact in the front of the engine. The cams are chain driven so they rattle more than whine.

If I understand you then you are saying that you can hit about 50 on the road, pull in the clutch but keep the engine revved to approximately the same RPM and the whine goes away? If so, then it could be a worn clutch slipping, maybe. The multi-plate wet clutches don't wear out all that easily (designed to be used in the friction zone a lot) but they do eventually wear out. Also, if someone has at some point put one of the "miracle" lubricants in instead of regular oil that can make them slip.

It could also be something in the transmission, I suppose, but unusual that it would whine only under load.

your read on my issue is spot on so your thinking clutch oh the bike has 16,500 but is an 03 you can hear it some through all gears

16k miles is pretty low to have clutch problems but somebody might have run friction reducing oil in it...that's about the only thing I can think of that fits that exact scenario, anyway.

Ordinarily I'd say try to isolate the noise further with a stethoscope but that's pretty hard to do when the noise is only present when riding!

It could also be a slightly bent shaft in the transmission (have heard of at least one person that had that issue on a 650) but I'd expect that to be present even when the clutch is pulled in.

Has this been happening for a while or did it come on suddenly? If it's been noisy for a while I guess I'd just ride it and keep an ear to see if it starts getting worse fairly rapidly. If it's stable it's probably not an issue. The other thing you might do is have a sample of the oil analyzed the next time you change oil. That can tell you if there is an unusual amount of metal in the oil. If there isn't a high level of metal in the oil then whatever is making the noise is probably benign. I think they can even tell you what kinds of metal are found and that could pinpoint whether it's a problem with the clutch or with the gears (assuming they are of different metals/grades of metal, and that I'm not sure of, it would require more research).

John

Just thought of something else it could be. If you've got a worn bearing on one of the shafts that could maybe cause the issue where it would whine only (or at least more loudly) when that shaft is loaded by torque. Again, an oil analysis should be able to tell you if there is an unusual amount of bearing metal in the oil, etc.

hey john did you know the 650 uses shell bearings to support the crank same as on the rods. but the 1100 uses ball bearings to support the crank. also the timing gear on the 1100 crank is replaceable on the 650 its welded on you have buy the whole crank if the gear is bad.

I wasn't aware the 1100 used ball bearings...assumed they both used ordinary bronze bearings. I learn something new every day.

That's crazy the timing chain sprockets being welded to the crank. Chains wear by nature and so do the sprockets they run on. It's like they were trying to ensure that people would junk the bike fairly early. :mad:

constant mesh tranys wine there's no stopping it. heaver full synthetic oils help some. some of the pricer bikes have high gear angle cut to stop noise but vstar gears are straight cut. they wine.
