There is no silver bullet in this game. There will never be a perfect stupid motorized bicycle. But its a lot of fun to tinker with and, in the words of a former employer, "Learn and grow together." The Revothingie could be an interesting way to teach youself to tune carbuerators. Maybe a guy could figure out how to dial in a fat low end on the power curve with jetting and float settings, different exhaust and intakes and whatnot. The Revo motor has as much merit as any other stupid bicycle motor out there, and as many shortcomings.
