I recently picked up a 71 honda CL100, from I guy I work with. The bike looks like hell but was only 40 bucks. I want to build a cafe racer with it and I was thinking of going 2-stroke. I want to get either a cr125 or cr250 dirt bike engine. It will mostly depend on what will fit and what i can find. My questions were is there an immediate problem with this idea, and how does one power a head light with a dirt bike engine.
