Im having problems with my yfz! sounds like valve tap but the valves are in spec and cam chain is also in spec, someone suggested tensioner, and changed it last night and didnt fix my problem. can anyone help me out

possible crank failure?

That's what I was thinking but I took it in and they figured out it was the clutch basket.

my buddys yfz sounded like a valve issue and the crank locked up the next race. hope you got everything figured out.

It could be a cam chain guide they wear out pretty quick. Its hard to say without looking at it but its worth looking at.
