I'll get some pics up soon as I get back into town to take them, just imagine about 10 needle bearings riding on top of your piston@ 8 or 9 thousand rpms, thats what it looks like. as far as jetting, I did a plug chop before going wot. and they looked tits. I have always used yamalube without a problem at all. The other cylinder and piston look perfect and perfect burn pattern on top of the piston as well. I don't know if it would be worth it to take the cylinder back to a machine shop to check if the bore is square, I think I'll just cut my losses on this one and move on. As far is compression I was running 168 psi. on both cylinders, running 110 trick racing fuel, timing was right at 3 degrees advanced , 270 main jets, @ 4800' elevation. I noticed when I took the cylinder off, there was no abnormal wear on the piston skirts that I could see. If anyone has any more info. I would appreciate it cause I am stumped!
