40 mm reproduction cylinder kit for Puch Supermaxi LG1 / LG2 mopeds. This cylinder also fits Puch Maxi or Puch X30 mopeds, as it is equipped with smaller exhaust ports. In this case, however, the corresponding exhaust with a narrower outlet must be fitted.
This tuning cylinder has more displacement and a larger inlet and outlet. As a result, the cylinder has significantly more intake than the original counterpart.
The piston has two piston rings.
You can find suitable add-on parts in the accessories section.
Attention: The stud bolt distance on the intake side is only 32 mm. On the original cylinder, this is 38 mm. The holes on the intake manifold must therefore be widened slightly in order to be able to fit it.
