I've got a 1971 Cb750 that I'll trade someone for a sweet top tank. Really want a Magnum ltd, or Derbi but will think about anything rad. It's a decent bike but I just don't ride it, have way more fun on my Magnum. I rebuilt the top end with a 2nd over piston kit, carbs cleaned synced and tuned, and put a powerarc electronic ignition on it. Cycle X 2 into 1 exhaust. Pretty much everything besides the lower end is new or rebuilt.
