Im selling a 50cc Puch Supermaxi euro cylinder (and piston included). Its pretty similair to a Korado cylinder but there are some differences. The transfers are pretty much the same size as a korado, intake port may be slightly larger but about the same, the exhaust port on this cylinder is definatly larger than ona korado. has an angled exhaust port like korado but has an angled intake like the puch 65cc hero kits. Also the fins are abit different than a korado. Anyway, its in good shape and comes with the matching piston. Somebody dremeled out the opening of the intake port so the guy ibought it from made an adapter plate to so you could still fit standard puch intakes (comes with that too). and also the fins on top were cut so you could put a puch intake on it i guess.
