Breather system is designed to control amount of oil
in head area and still maintain necessary vacuum in
crankcase.
When piston moves downward, crankcase gases are
pushed past reed through mesh fi lter into intake system.
Upward travel of piston closes reed and creates a low
vacuum in lower crankcase. Any oil separated out
through fi lter drains back into crankcase.

cover.

3. Remove breather cover spring, disc (breather reed),
