It is the cg engine that was quite a good engine as it retained the pushrods and it was robust. These little bikes can be supped up cheaply.Wonder if you could drop a Bonnie engine in it. Ride free Joe
It’s the tank, seat, exhaust and quite a few other things too that bends your mind to see it that way.
Yes the cb had camchain but good little machines I liked the cg as they just went on forever. Regards Joe
