    Break In ?

    I had the TRX bored a little. I have added a K&N air filter. Hetrick exhaust. Thinner head gasket. What is the best way to go about breaking in the new bore and rings? I bought the 82 85 88 main jets. Any help would be appreciated.

    I'm no expert, but I just got Kyle's quad back yesterday and Eric from ICRacing told me to run 3 cycles of 15min (at idle)each with a fan on the bike, letting it cool down completely between cycles and he said it would be good to go.

    i am no expert either but i would have to disagree i would think idle for a cam breakin is a no no.. and a piston ring and bore breakin i think you would want the rings to expand so i would vary the throttle while moving for airflow over the engine
