Right now I'm having some trouble with valve clearances. Luckily I might know how to fix it. I kept thinking the cam was jumping the timing (which it might still be by a link or two) because every time the engine seized the piston was up and the valves were down. That was before I remembered that there are two crank rotations for every single cam rotation.
But the problem remains that the valves are now hitting and they weren't before I took the thing apart. I'm going to raise them up so they dont get bent and work them back down as I need. I can't afford a new set of valves ($100, half the value of the bike).
