Hey I'm trying to get my motorbike up to 80mph. I installed a window port piston but it's the only thing bogging it down n making problems. 1yr of BS. I tried a HP carb, a PZ22, etc. But there's gotta be a way to increase performance of 80cc engine. I want higher HP, higher low end top end speeds, faster acceleration, better control, etc. What's everything u have to say bout that?
How does your engine of choice direct valve cover gasses? Replicate it as best you can. I don't have a stock engine to refer to. Photos of the engine you settle on for your build. ON YOUR thread.
