Re: New (old) stuff
I don't know. Seems like 43mph with a 44t on a 49cc is wishful thinking. Especially with the simple modifications you have going on. Anyways we are taking about an engine that has 4/3 the displacement. It's going to have more power in stock form when set up properly any day of the week. No replacement for displacement. I'll race ya with my 66cc!
