Professionally machined racing E50 4-bearing engine housing set with GME (housing-membrane intake) for your Puch moped / moped.
This racing case is the «der.prüfstand» edition, which is produced exclusively for mofakult. The massive 39.5 x 26 mm intake ensures plenty of steam with the included diaphragm system.
No adjustments to the Maxi frame are required to install the engine. Due to the narrow upper surface of the diaphragm box and the ability to rotate it 180 degrees, it is possible to align the nozzle and carburetor mounted on it slightly steeper or flatter.
In addition to the crankcase, the set includes the reed valve box, the Stage6 reed valve and the intake manifold.
Optionally, you can also order a complete Stage6 carburettor with flange or just the matching adapter for your carburettor.
For even more power, you also have the option of ordering the housing spindled. This makes it possible to fit large 47 mm cylinder kits such as those from Gilardoni italkit, Airsal or Parmakit.
For a closer look, you will find the parts listed individually below.
