Giant 47mm Parmakit for Puch mopeds. Aluminum with nikasil plating. Split windows for the intake and exhaust. Single ring piston. This WILL require case boring to fit onto an e50 or za50. It does have the angled exhaust port. Comes with an equally giant head to keep it cool. Dare to be different!
Comes with cylinder, head, piston, ring, pin/clips, studs, and gaskets.
