The owner of the White one I built and the other 300's I am in contact with broke nothing. There isn't much to brake on the 2 stroke. The 50 hr rebuild is a 4 stroke recommendation, not the 2 stroke. The 2 stroke is happy singing it's song for hours. I personally will put in a fresh piston every fall. 5 Bolts and a cer clip, $180 and takes about an hour. The most important thing and only thing really, is air/fuel. Don't just lean it out until it "feels right". On long WOT pulls, you could squeak it. I recommend tuning with an AFR at 13 to 13.8 or an EGT for 1200f. Then "Braap Braap", go play!
