Servicing Your Honda 146
Air Cleaner
Refer to Safety Precautions on page 107.
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 ATV’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.
Proper air cleaner maintenance can prevent premature engine wear
or damage, expensive repairs, low engine power, poor gas mileage,
and spark plug fouling.
NOTICE
Improper or lack of proper air cleaner maintenance can cause poor
performance and premature engine wear.
