Reproduction Honda CB750 spark advancer assembly. This part has been discontinued by Honda for a long time. Now there's a reproduction available! No more tracking down a questionable used one or searching for replacement springs. Of course after installing this you'll have to reset the ignition timing, but you knew that already. Don't forget to lube the cam.
