I just rebuilt my '97 GSXR750 . I have to shim my valves all over again because they got mixed up. My manual doesn't say what the clearance between the back of the lobe and the top of the bucket are supposed to be. Is that the correct place to measure? Also, does anyone know the proper valve to piston clearance? I bored it two over and gave it a set of Wiseco high-compression pistons and I'm worried about my clearance.Thanx in advance!
