Air Filter/Pre-Filter Service
It is recommended that the air filter and pre filter be
replaced annually. When riding in extremely dusty
conditions, replacement is required more often.
The pre filter should be inspected before each ride, and if
required, cleaned using the following procedure:
1. Lift up on the rear of the seat.
2. Pull the seat back and free of the tabs.
NOTE: When reinstalling seat, make sure the slots
in the seat engage the tabs in the fuel tank.
3. Remove (6) clips (A) from air box cover and remove
cover. Inspect the gasket. It should adhere tightly to
the cover and seal all the way around.
4. Loosen clamp and remove air filter assembly.
Cleaning:
5. Slip the pre-filter element off of main element. Clean
the pre filter with hot, soapy water.
6. Rinse and dry thoroughly.
7. Inspect element for tears or damage.
8. Inspect main filter and replace if necessary. If the filter
has been soaked with fuel or oil it must be replaced.
Installation:
9. Reinstall pre-filter element over main filter. Be sure the
element covers entire surface of main filter without
folds, creases, or gaps.
10. Reinstall filter on main filter mount. Place filter clamp
over the assembly and tighten.
NOTE: Apply a small amount of general purpose grease
to the sealing edges of the filter before reinstalling.
NOTE: The air filter should rest on the filter support.
Proper placement of the air filter is important to prevent
rattles and air leaks. See Illustration above.
11. Install air box cover and secure with the (6) clips.
