I want to put together an old school mini-bike; you know, a project thing for me and my grandson to work . Seems like they are available as kits or finished form. I'd like to find one that we could fix up, repaint, maybe put a little bigger engine on it so my fat-body self can ride it a little too. Anybody know of a local source for this kind of project or where I might find an old one we could restore one together? Here's the kind of thing I'm talking about; the old type that had the six inch fat tires and an old lawnmower type of engine.
