Air Cleaner
Refer to Important Safety Precautions on page 23.
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 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.
Using the wrong air cleaner may result in
premature engine wear.
Proper air cleaner maintenance can prevent
premature engine wear or damage, expensive
repairs, low engine power, poor gas mileage, and
spark plug fouling.
Improper or lack of proper air cleaner
maintenance can cause poor performance and
premature engine wear.
