i just got, kind of "inherited" a cm400, it seems to be in pretty good shape with new tires, sprockets and chain. are there any performance upgrades that can be done with this bike? i was also thinking about a cafe build for it. this bike WILL be sold when i finish it as i dont think me, as heavy and big as i am, should be riding a 400, i'd look like a monkey screwing a football lol. anyways the bike was free and i'm looking for ideas, i even thought about doing a rigid chopper.................who knows.
