I have an 80 parmakit thats been seized by the master of shippinig. I cleaned it up the best I could and then went pretty big on the porting. Definitely has to dings in it, but I have definitely seen much worse run. Sold the bike before I ever got it running. Needs a ring. Fairly certain a gila or 80 metra dykes ring will work. $50?
ZA 50 motor. In pieces, but all there. Crank seems to be in really good shape. Still has good life in it. The cases are been bored out to take an 80 kit, and one side of the cases as been built up with JB weld for bigger transfers. Jb weld might still need a little sanding. I cant remember. Ummm, make me an offer?
