Powerful racing kit with 45 mm bore and reed valve intake suitable for various Puch mopeds and small motorcycles.
The housing does not need to be spindled for use. To use this cylinder, however, the racing kit lock must be removed.
Ø outside intake manifold: 20 mm
Ø inside intake manifold: 16 mm
Scope of delivery as shown in Figure 1.
Since experience has shown that the supplied steel diaphragm plates can break, we recommend replacing them with carbonite diaphragm plates.
You will find these in the accessories along with other suitable parts such as a larger intake manifold.
