Hello fellow TT'ers. I know this has been covered before, but due to the search being down right now I am asking again. I've noticed lately that my 2000 yz426f is starting to make some noise. I'm suspecting that it may be the clutch because it only makes the noise under a load. If the clutch is in, no noise. If I am just idling, nothing. Slowing down, nothing. But when I accelerate or am riding at a constant speed there is almost a griding/rattling noise. Is this the clutch? I've also heard of the cam chain going bad on these bikes. Could it be that? Thanks in advance!
