Engine case PARMAKIT suitable for cylinder Parmakit SP09, W-Force. SixtySix etc.
New engine case that has a larger crankcase diameter and a larger cylinder base mount from the factory.
This means that a reinforced crankshaft with a larger crankshaft diameter (max. Ø87mm) can be fitted without modifications.
The cylinder base mount has two offset diameters.
The bigger one has a diameter of Ø65.5mm and is 7mm deep and therefore suitable for the Parmakit W-Force with Ø60mm (144ccm).
The second diameter is Ø63mm and fits the 135cc version of the W-Force cylinder.
The housing has a mount for the classic 2-pull gearshift of the Vespa V50, PV, ET3 and PK XL models.
Due to the enlargement of the crankshaft diameter for crankshafts up to Ø87mm the rotary valve inlet is no longer usable.
The housing is therefore intended for use with a diaphragm intake.
Alternatively, the use of a cylinder with diaphragm inlet directly on the cylinder is possible.
