Help me build a gas power (scooter, bike, something)

[vaironl]

Hello all,

Lately I've been pretty bored with my college classes and want to do something more fun with my time than spend my day on Facebook or a crappy game. I recently saw an interview with Horacio Pagani in which he mentioned a gas powered bike he built and also how fun building even small wood models of cars can be a very satisfactory thing todo.

So I kind of want to try and experience this while also going a cheaper route than modding my car, which has been at times a bit more costly than I wanted to. At the same time I want to learn the basics of how certain mechanical things work. So does anyone have any pointers as to what would be a be a low cost and fun project? Which is along these lines of maybe taking the engine of something small and slapping it onto some kind of bike, or scooter ?
