Yeah. Wouldn't it have made more sense to put the engine and gas tank in back? I mean, think of the weight savings (not to mention radically less mechanical loss) you'd have by not having that shaft running the length of the bike. That would also lighten up the front end [sic], and give it quicker steering. And next time, the frame should be twin-spar alluminum--ya' know, for stiffness. (Just imagine for a moment.) Finally, he ought to have powered it with a Jap 600cc engine.
