Default Re: 43mph 48cc stock internals +- 1500 miles later

I'm currently using a 36 tooth sprocket at the back and standard infront. 26" bicycle wheels and tyers. Reason I caught that speed was mostly due to the free flowing exhaust . Running roughly 9300rpm at 43mph . Also on a reasonable downhill.
