Fan-cooled 38 mm original cylinder compatible with your Puch X30 Velux, X30 NG-2AH, or X30 NG-2A moped.
This reproduction cylinder is equipped with a seal, which is why it can be used as an original cylinder. 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 so that the cylinder seals properly. We recommend using Wekem 2K liquid metal for this, 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 in the accessories section.
A good, affordable standard replacement part. GPO – GOOD PARTS ONLY.
