I hadn't considered that when it comes to two strokes....As of now I'm building up a sweet rat bike using all the vintage stuff I can, it'll get motorized after a good shakedown since I want to have a good platform. If when I install the motor I find that the cranks are too narrow, guess I'll have to replace....fortunately this setup was pretty cheap. By the same token I'd LOVE to have some ratty old block pedals on here but I know that when the motor comes, I'll want something with GRIP, probably some modern BMX beartrap style.
