Air Filter / Pre-Filter Service
It is advisable to replace the filter when it is dirty. However, in
an emergency, it is permissible to clean the main filter if you
observe the following practices.
• Never immerse the filter in water since dirt can be
transferred to the clean air side of the filter.
• If compressed air is used never exceed a pressure of 40
PSI. Always use a dispersion type nozzle to prevent
filter damage and clean from the inside to the outside.
It is recommended that the air filter and pre filter be replaced
annually. When riding in extremely dusty conditions,
replacement is required more often.

1. Remove the seat to access the airbox cover.
2. Unscrew the two knobs retaining the airbox cover and open
the cover.

Cleaning:
4. Slip the pre-filter screen off of main element. Clean the pre-
filter with hot soapy water.

Installation:

tightly to the cover and seal all the way around. Replace
