  1. **I am stumped on an XR 80 (pre-cdi). Replace the piston kit, and ended up replacing the head. Need advice on setting the timing. I have heard of the "O" mark @ 12:00 and the "T" at the triangle and have followed that. However the bike still runs very eratic, won't idle down, won't follow the throttle etc. Also heard the cam lobes needed to be in the down position while aligning the timing sprocket and the flywheel. Help.
