Complete set:
High-end racing crankshaft 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, the additional stroke gives your engine more torque and compression and thus tickles the last horsepower out of the cylinder.
High-quality and precisely fitting, 975 gram full cheek crankshaft, which has proven itself in various load tests. This was designed for use in engines with a large increase in power. All the balancing holes in the cheeks have been sealed with aluminum inserts for maximum pre-compression.
The solid connecting rod is fitted with a more stable 16 mm connecting rod pin, which is hollow on the inside for better balancing.
In addition, the connecting rod bearings are silver bearings, which have excellent emergency running properties.
The following points should be noted when using this crankshaft:
- The use of a 0.5 mm thick stroke plate is essential to compensate for the additional stroke. We also recommend using sealant between the seal and the housing/cylinder. You can also find a suitable sealant in the accessories section.
- When installing, observe the crushing 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. For this reason, the oil seal on the crankshaft end should either be glued in with 2-component adhesive or secured with the retaining plate.
- Running in the crankshaft: Run the engine for 30 minutes under low load with a slightly richer mixture.
- When using 45 mm cylinder kits, depending on the model, pre-compressed air may enter the intake port through the holes in the piston.
