Bladed 40 mm cylinder kit with 12 mm piston pin for your Puch X30 Velux and Puch X30 NG-2AH moped / moped.
With its cylinder neck diameter of 43 mm, the cylinder also fits small engine wheels such as MS, VS, DS, VZ and M50.
The racing cylinder kit without sealing includes cylinder, piston kit, gasket set and studs.
Note: For the Puch Velux engines, the small slot at the sealing surface to the cylinder must be filled so that the cylinder kit is sealed.
We recommend using Wekem 2K liquid metal for this purpose. Please note the installation direction when assembling. The piston is inserted with the arrow pointing towards the outlet on the exhaust side.
