I have a 2000 TTR 125 that had a stuck piston, so I took apart the head honed the cylinder and replaced broken valves. At dusk I started it on the first kick, but the valves were clacking bad. I decided to wait until tomorrow to adjust them, and that is what I did. I put them to what the manual said (Intake 0.08-0.12, Exhaust 0.10-0.14), but now it won't start. Did I do something wrong?
