SERVICE
AIR FILTER
This motorcycle is equipped with a dry paper air
filter. In order to function properly, the air cleaner must provide an
airtight seal between the air cleaner cover and backing plate. Without
this complete seal, dirt contaminated air may enter the engine causing
rapid wear and possible engine failure. The air filter must be serviced
or replaced at 500 miles and every 2,500 miles thereafter. A dry-
paper filter cannot be cleaned with any type of solvent or water. If
the air filter is dirty, service using the following steps:
NOTE: California models are equipped with a charcoal impregnated air filter. For servicing,
follow the dry paper filter procedure.
1. Remove the three Phillips screws attaching the air cleaner cover to the air cleaner
back plate.
2. Remove air filter from the air cleaner back plate.
3. Tap the filter on a flat surface to dislodge any large embedded dirt particles. Use low-
pressure air, 15 psi or below, to clean the filter by blowing air through the filter from
the inside out. Hold the air nozzle at least three inches from the filter to avoid rupturing.
4. After cleaning, reinstall air filter assembly, tighten the three Phillips screws thoroughly,
seating the air cleaner element.
5. Never operate the engine with the air filter removed.
