45mm 70cc Airsal Cylinder kit for Puch Mopeds (such as Maxi, Magnum, Newport, Korado, and others) with E50 or ZA50 engines! Comes with single ring 45mm piston, 45mm x 1.5mm GI piston ring, 12mm wrist pin, 12mm wrist pin clips, four studs, and full gasket set. This cylinder kit is the de-facto entry level kit for Puch bikes. It's easy to install as far as kits go, adds solid power across the entire rev range, and pairs well with a large variety of carburetors and exhausts. While you can run this cylinder with a stock pipe or carburetor, performance won't be the best - we'd recommend upgrading to a 15mm-20mm carburetor and an expansion-chamber exhaust. If you're building on a budget, the Mikuni VM18 and Tecno Boss are solid choices.
