AIR FILTER
Inspect the air filter regularly. When it becomes dirty or contaminated discard it and replace with an
equivalent new part. The air filter is a reusable washable type, wash the dirt out with a mild detergent,
rinse thoroughly and dry with a clean towel.
SPARK PLUG
Spark Plug Recommendation
The recommended standard spark plug is satisfactory for most riding conditions. However, If you plan to
ride for extended periods at high speeds or near maximum power (high engine rpm) in hot climates, or
plan extended riding in cold cli-mates, a “colder” or “hotter” heat range plug may be recommended.
NOTICE:
Using spark plugs with an improper heat
range can cause engine damage.

Removing or Replacing the Spark Plug
Before removing the spark plug clean any dirt from around the spark plug base.
Carefully disconnect the spark plug wire cap.
Do not pull on the wire as this may damage the conductor within the wire causing high resistance
and reduced firing voltage.
Remove the spark plug with a spark plug wrench.
