Air Filtration System

Air Filter Maintenance

To maintain the highest performance from your
engine and to reduce excessive wear that could
cause engine failure, the engine requires a
continuous flow of clean air. Air is taken into the
engine through air filters to clean the air prior to
mixing it with fuel in the carburetor.
During normal operation the filters accumulate
dirt from the air and will need to be cleaned to
maintain the proper air flow. The filters should be
cleaned every 30 days, more often if you ride in
a dusty or dirty environment and the elements
should be replaced every year.
The air filter box is located on top of the engine
below the seat. It is a black cylinder about 4"
across and is attached to the crankcase with two
bolts and the carburetor by a tube.

To clean the filter

1. Remove the air filter box covers, (LH and
RH).
2. Remove the filter elements from the air box.
3. Wash the elements in a non-flammable
solvent such as Air-Filter cleaner from your
local auto parts dealer.
4. Dry the elements completely before
continuing.
