WORKING PRINCIPLE
The engine breather system is located on the RH cover of the crankcase. A connecting hole
directs the engine breathing into a chamber in the RH cover which has an inbuilt deflector
to deflect the oil that may come along with the fumes from the crankcase. This oil gets
drained through a small hole provided at the bottom of the breather chamber.
The emission passes through the deflector chamber and goes to the air filter housing and
passes through the inlet manifold back into the cylinder head.
