Puch Airsal 38mm "50cc" Cylinder Kit

Puch Airsal 38mm 50cc cylinder kit. For E50 or ZA50 engines.  Aluminum, nikasil plated cylinder kit. Comes with a 2 ring piston.  These need to be spaced out a bit so the piston does not hit the cylinder head. Will also not work with any o-ring head because of the decompression valve.  Comes with cylinder, piston, rings, pin/clips, gasket set, and new intake/exhaust studs.  Airsal 02031138
