Looking for a little feedback. Have a Yamaha KT 100 ran in Junior sportsman class. Has anyone ever heard of the coil or TCI causing motor to stick on fresh rebuilt or even after a couple hours on motor
Never. If they fail you just get no spark. As long as you got fuel it should have nothing to do with a stick.
Now if the ign rotor was installed without the key it could have slipped. I guess that could increase timing enough to get into detonation.
Stick on a fresh rebuild could be bad communication between engine builder and racer. Builder sets it up thinking it will get a long break in and the customer thinks it’s ready to race.
If I don’t know what’s going to happen to the engine after it leaves the shop I put in extra clearance.
Ignition could be set up with too much advance and too little rotor clearance. Might be a contributing factor.
Did you put oil in the gas?
