The engine is provided with a dry sump forced lubrication sys-
tem with a main oil pump with integrated pressure regulator.
The oil pump sucks the motor oil from the oil tank via the oil
cooler and forces it through the oil filter to the points of lubrica-
tion in the engine.
The surplus oil emerging from the points of lubrication accumu-
lates on the bottom of crankcase and is forced back to the oil
tank by the piston blow-by gases.
The oil pump is driven by the camshaft.
The oil circuit is vented via bore on the oil tank.
The oil temperature sensor for reading of the oil temperature is
located on the crankcase, on the mag side of the engine.
The oil pressure sensor for reading of the oil pressure is located
on the ignition housing.
