    Explanation old and new model crankshaft E50 engines

    • Suitable for Puch Maxi S / N, as well as Supermaxi LG1 mopeds with a 1-speed E50 engine.
    • This special crankshaft has 1 mm more stroke, which is an absolute world first in the Mofatuning range!
    • The extra hub gives your engine more compression and tickles the last horsepower out of the cylinder.
    • Made by the quality brand swiing - swiss ingenious.
    • High-quality and precisely fitting, 990g heavy full crankshaft, which has proven itself in a variety of stress tests. Designed for use in high power engines. All balancing holes in the cheeks were closed with aluminum inserts for maximum pre-compaction. The massive connecting rod is provided with a Ø16 mm connecting rod. In addition, the conrod bearings are silver bearings, which have excellent emergency running properties.

    When using this crankshaft, the following things should be noted:

    • The use of a 1 mm thick lifting plate (60060) is essential. You can find matching models below in the accessories. In addition, we recommend using sealant between the seal and the housing / cylinder. This can also be found below in the accessories.
    • When installing, observe the crimping edge dimension (distance piston - cylinder head at TDC). This should not be less than 1 mm.
    • Due to the longer stroke, the pressure in the crankcase increases. Therefore, the ignition-side oil seal should be glued with 2-component adhesive .
    • Retracting the crankshaft: Run the engine for 30 minutes under light load with a slightly richer mixture.
