Description

CRANKSHAFT EGIG170 FOR VESPA SMALLFRAME V50, V90, PV, ET3, PK...

High quality crankshaft needed for the EGIG 170cc cylinder kit for Vespa Smallframe. With this kit even a 50cc stock engine can be upgraded to a touring and everyday 170cc. The power at the rear wheel is, depending on the used exhaust and carburetor around 20-25HP and up to 24Nm (without milling work on the engine or cylinder). The only necessary modification to the engine case is to lower the edge of the case that rises above the sealing surface at the base of the engine cylinder. This is taken down to 2mm (file/Dremel is sufficient, it does not have to be planned up to the sealing surface).

The cylinder is built together with this crankshaft as a diaphragm controlled engine. This means that the intake for the mixture is done automatically by a diaphragm box screwed to the cylinder. No timing (as with the rotary valve) must be considered.

Stroke: 51mm
Diameter crank webs: Ø83mm (therefore no spindling necessary)
Connecting rod: Primatist CNC forged connecting rod
Connecting rod length: 115mm
Required bearings for the crankshaft: Both sides 6204
Oil seal clutch side: 27-47-6
High quality crank pin and needle bearing

CONCLUSION: Super simple solution for powerful and durable touring engines with a lot of displacement
