Crankcase Breather
Refer to Important Safety Precautions on page 23.
Service more frequently if your CRF 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.
1. Remove the crankcase breather tube plug (1)
from the crankcase breather tube (2) by sliding
the clip (3) and drain deposits into a suitable
container.
2. Reinstall the crankcase breather tube plug.
