Breather / Oil Separator
The breather / oil separator is located on the upper rear cab support. This system provides ventilation for the valve cover
and engine crankcase to the air box. A one-way valve (A) allows pulses from the crankcase to travel in one direction
only, thereby vacuuming the crankcase. NOTE: Over-filling of crankcase will result in oil in the air box. Always keep oil
volume at recommended level.
