Air Cleaner
Refer to Safety Precautions on page 19.
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 genuine
Honda air cleaner specified for your model or an
air cleaner of equal quality.

repairs, low engine power, poor gas mileage, and

maintenance can cause poor performance and
premature engine wear.
