Powerful racing kit with 38 mm bore and reed valve inlet suitable for various Puch mopeds and small motorcycles.
The housing does not need to be spindled for use. To exploit the full performance, we recommend fitting at least a 15 mm carburetor and a racing exhaust.
Ø outside intake manifold: 24 mm
Ø inside intake manifold: 20.5 mm
Scope of delivery according to figure 1.
As experience has shown that the supplied steel diaphragm plates can break, we recommend replacing them with carbonite diaphragm plates.
You will find them in the accessories along with other suitable parts.
