no break in needed, just grip it and rip it. of course take it easy for a few tanks but not like a nitro were you heat cycle and apply throttle for 2 seconds and then brake for 2 seconds. None of that crap. just crank and drive like you normally would but hold off on full wide open extended throttle untill tank 3 or so. Its just like your weed eater motor you dont need to break those in, nor do you need to break this one in.

slight break in is what im sayin, just crank and drive and hold off on going full throttle till after a couple of tanks. clean your filter/s oil and grease and check the bolts and thats all you need to do. once you tune it its tuned you dont even need to bring the tuning screw driver with you after its tuned. Unlike the nitros where all you do is tune so you can run it for a few mins then retune the next time you start it up.
