Spark Plug
Use only the recommended type of spark plug in the recommended
heat range.
NOTICE
Using spark plugs with an improper heat range can cause engine
damage.
Refer to
Safety Precautions
on page 103.
1. Remove the seat (page 114) and tank cover assembly (page 115).
2. Clean any dirt from around the spark plug base.
3. Disconnect the spark plug cap (1). Take care to avoid damaging
the spark plug wire when disconnecting the cap.
4. Using a spark plug wrench provided in the tool kit, remove the
spark plug.
5. Inspect the electrodes and center porcelain for deposits,
corrosion, or carbon fouling. If the corrosion or deposits are
heavy, replace the plug. Clean a carbon or wet-fouled plug with
a plug cleaner, if available, or a wire brush. Inspect the spark plug
electrodes for wear. The center electrode (2) should have a flat tip
and sharp edges, and the side electrode (3) should not be eroded.
If the electrodes and insulator tip appear unusually fouled or
burned, we suggest that you contact your dealer.
