Recently I rebuilt the top end of my 01 yz125, re-sleeved wiseco piston. there was no vertical free play in the rod. I even took off the stator cap and and tried to jiggle the cam, no play either.
After running it in the other week I noticed a pronounced wurring sound coming from the bottom end. I removed the spark plug and when turning the engine over wiht the kick starter the noise is apparent. could this mean that the crank bearings are on the way out? the mechanic at shop said it was the piston just settling in but I'm not 100% buying what he said.
Any ideas,? I mean its probably due for a bottom end rebuild anyway .
