So, I took the bike out ALL night with my friend and we raced all over town. Im worried though, I started out topping at 41, I made a new cylinder as my old one had scratches in the plating around 300 miles. The new one I ported "better" and only managed 40.25 (44 tooth) as the night went on my top speed kept dropping lower and lower and lower and I ended up topping out around 36.5... Is the cylinder wearing out THAT fast? I don't know what else it could be. Also 41mph was the BEST recorded top speed on 44 tooth to date. Anyone ever logged any faster on GPS? I have done EVERYTHING you can do to this motor.
