I have had this annoying problem with my 96' bike pretty much from when I bought it some months ago. When the bike is warm and had a pretty good blast, it seems to delevop a lot of drive train noise. Kinda like a buzzing/whining sound, especially on left hand cornering. This noise dissapears if I engage the clutch. The bike's done 14,000 miles on the original chain, so I thought it may have been just c&s wear. I have just had new c&s fitted by my local Kawa dealer. This has helped only a little, but the noise is still very noticable. They checked my clutch and it seems to be ok. I did not notice any clutch slip anyway. Any ideas, as this is spoiling an otherwise great bike.
