I recently purchased this roller and am going to try to build it in a usable driver. Note I did post this over on the what is it thread I just bought a used moto with a predator 212 and decided I want another bike. I'm also trying to get some experience on this build for future builds. I'm new to mini bike but not really to working on stuff and have a good selection of tools including a welder. I'm hoping to get document my project and pick the collective brains here. I think the first thing I would like to do is start getting the parts together. First question is there any reason for this build not to go with a predator 212? I don't find them as attractive as some the older engines but I'm not really going for a vintage look or a restoration here. Probably in future builds I want to try different motors.
