Crankcase Breather; Draining - Honda CRF450L 2019 Owner's Manual & Off-Road Handbook

Refer to Important Safety Precautions on page 33.
Service more frequently if your motorcycle is
ridden in the rain or often at full throttle.
Service the breather if you can see deposits in the
transparent section of the crankcase breather tube.
If the breather tube overflows, the air filter may
become contaminated with engine oil causing poor
engine performance.
