Fan-cooled 38 mm gray cast iron cylinder compatible with your Puch X30 Velux and X30 NG-2AH moped.
This replica cylinder features a larger intake port than the original cylinder, making it a simple tuning option for your fan-cooled Puch engine. The cylinder is made of gray cast iron and has a sandblasted surface.
For Velux engines, the small slot at the sealing surface must be filled with casting material to ensure the cylinder seals properly. We recommend using Wekem 2K liquid metal, which you can find in the accessories section.
Note: The cylinder is shipped loose and without a piston, gasket set, studs, or other mounting parts.
You can find matching gaskets, pistons, cylinder heads, and 2K liquid metal among the accessories.
A good, affordable standard replacement part. GPO – GOOD PARTS ONLY.
