**PLEASE NOT THAT DEPENDING ON AVAILABILITY THE BORE SIZE MAY BE MOVED UP TO 69mm IN 0.5mm INCREMENTS**
Two-stroke engines get more power from porting than they do from increased size, and this kit combines both. Our porting is the best in the industry, guaranteed. When you have that AND the larger bore, plus increased compression from the Cool Head, you have a top end that will stomp the competition, and because it is a stock cylinder they will never know it's coming! You can get 20+ hp more, depending on what else is done to the engine.
