Fan-cooled 38 mm cylinder kit with a 12 mm piston pin. This reproduction cylinder has a larger intake port than the original cylinder.
Compatible with Puch X30 Velux and Puch X30 NG-2AH mopeds.
Note: For Velux engines, the small slot at the sealing surface must be filled with casting material to ensure the cylinder kit is airtight.
We recommend using Wekem 2K liquid metal, which can be found in the accessories section.
Note: Please observe the installation direction during assembly. The piston is installed with the arrow pointing toward the exhaust on the exhaust side.
A good, affordable standard replacement part. GPO – GOOD PARTS ONLY.
