The oil pump of the PX models works speed and load dependent. The higher the speed and/or the further the throttle is opened, the more the pump delivers two-stroke oil into the crankcase.
Varying pump impellers are used depending on the displacement.
These are distinguished by markings on the top of the gear:
1 notch = PX80
2 notches = PX125
3 notches = PX200
4 notches = PX150
The pump impellers differ in their angle on the surface, which determines the stroke of the pump. The pump wheel of the PX200 delivers the most, but with ~1:33 it is also very greasy, even for most tuning cylinders.
The pump wheel of the PX125 delivers on average around 1:50 and can therefore also be used in higher capacity engines without any problems. It is also suitable to equip tuned PX80 engines with a larger oil output. Their delivery rate of ~1:70 is rather in the lean range.
