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.
Spark Plug Inspection & Replacement
Refer to Safety Precautions on page 137.
1. Lift the cargo bed (page 94).
2. Remove the air cleaner outer cover (page 154).
3. Clean any dirt from around the spark plug base.
4. Disconnect the spark plug caps. Take care to avoid damaging the
spark plug wires when disconnecting the caps.
5. Using a spark plug wrench provided in the tool kit, remove the

spark plugs.

6. 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 should have a flat tip
and sharp edges, and the side electrode should not be eroded. If
the electrodes and insulator tip appear unusually fouled or
burned, we suggest that you contact your dealer.
