I just put back together a 01 kx100 for my son. New piston, rings, shaft, little and big bearings, and stator. ( i broke the stator popinh the magnito. the bike rolls over fine and shifts well. It is hard to start and when it starts it knocks and runs bad. I am afraid to idle more than a few seconds. could thisbe timing of the new stator? Is setting the timing as simple as loosening the stator and turning it. I am going to try this when I get home tommorow, is there something else I should check, such as exaust valve.
