Default Re: 40 MPH Club

Coaxing 40mph out of a 49cc 4 stroker will be a good challenge... it can be done but won't be quite as easy...
With some careful port work, bigger valves,bigger carb, a tuned pipe (stepped type header), and a cam (if available ) and give it lots of compression and it should make it, best bet would be to set it up to make lots of top end power, lots of rpm, and gear it down and/or find a way to make a cvt work and 40mph should become fairly easy to reach. You could run it on methanol or even a nitro blend will also help.
