Expanded 38 mm cylinder kit with 12 mm piston pin. This reproduction cylinder is provided with a seal, which is why it can be used as an original cylinder.
Fits Puch X30 Velux and Puch X30 NG-2AH mopeds.
Attention: On Velux engines, the small slot in the sealing surface of the cylinder must be filled to ensure that the cylinder kit is tight.
The Wekem 2K liquid metal, which can be found in the accessories, is recommended for this purpose.
Good, inexpensive standard spare part. GPO – GOOD PARTS ONLY.
