Air Cleaner
Refer to Safety Precautions on page 27.
The air cleaner uses polyurethane inner and outer
pieces which can't be separated.
A dirty air cleaner will reduce engine power.
Proper air cleaner maintenance is very important
for off-road vehicles. A dirty, water-soaked, worn-
out, or defective air cleaner will allow dirt, dust,
mud, and other impurities to pass into the engine.
Service the air cleaner more frequently if you ride
in unusually wet or dusty areas. Your Honda dealer
can help you determine the correct service interval
for your riding conditions.
Your CRF's air cleaner has very specific
performance requirements. Use a new Honda
Genuine air cleaner specified for your model or an
air cleaner of equal quality.
NOTICE
Using the wrong air cleaner may result in
premature engine wear.
