ANyone that has timed a warrior remember if the cam sprocket mark is lined up with the casting mark just BEFORE the pointer or just AFTER the pointer. NO matter what I do the timming marks are always a tooth off the mark - it is frustrating, I think yamaha casting for these cylinder heads is so old the marks are no longer right!!!. Please if you have run into this problem.

 

Stretched timing chain. Mine were bout half a link off. Advanced = torque, retarted = top end (also more likely to hit a valve).
