Cylinder cover with 43.50 mm combustion chamber diameter suitable for rebuilt Puch Maxi S/ N, Puch X30 Sport NS/ NL, Puch X30 Sport N-2AH and Puch Supermaxi LG1/ LG2 mopeds/mopeds.
A good reproduction product of the original Austrian version with slightly larger cooling fins, colloquially known as the "new model", which is cooled by ambient air (airstream).
The head with integrated, heat-resistant FPM sealing ring is the best choice for your 43.5 (64 cc) Polini racing kit with large cooling fins.
The contact surface for the sealing ring of the spark plug and the contact surface for the stud nuts are machined flat.
