I've got an old GSX250 sitting in the garage, and I've been toying with the idea of restoring it for a while now. Before everyone steps in and tells me not to waste my time with it, I want to do it more as a learning experience than anything else, and because my brother is going to want a bike to ride in the next twelve months or so. I have a fair understanding of the basics of how bikes work, and a relatively good technical understanding of the moving parts as well, but it's all theory based. What I'm after is a book that covers the lot. I don't need massively detailed explanations of absolutely everything, because I can research any problems I come up against, but it'd be nice to have a basic guide to the motorcycle from a technical point of view. I'm particularly interested in understanding more about fuel and electrical systems so I can teach myself through a ground up restoration. So - has anyone got such a book, or come across one in their travels?
