BREATHER VALVE
Remove Breather Valve
The function of the breather is to create a negative pres-
sure in the crankcase, which prevents oil from being
forced out of the engine through the piston rings, oil seals
or gaskets. A sealed-type crankcase emission control
system is used to prevent blow-by gases from emitting in
the air. The blow-by gases are drawn into the clean side
of the air cleaner through the crankcase and the cylinder
head and mixed with the clean airflow, and subsequently
come into the combustion chamber through the carbure-
tor. Oil is primarily separated from the gases while pass-
ing through the inside of the rocker chamber from the
crankcase, and secondly separated from the gases in the
breather chamber, and then brought back to the crank-
case.
A. Remove the cylinder head assembly (see Remove
Cylinder Head in Section A).
B.
Unscrew the breather valve screw [A].
