Spark Plugs
Spark Plug Recommendations
Replace spark plugs at the intervals recommended in the
periodic maintenance table. See page 52. Always replace
spark plugs in pairs.
Spark Plug Inspection
CAUTION! Wear face protection when using pressurized air.
1. Make sure the engine is at room temperature.
2. Disconnect the spark plug wires by pulling upward on the
spark plug boots.
3. To prevent any debris from entering the engine through the
spark plug hole, use pressurized air to clean the area
around each spark plug before removing it.
4. Remove the spark plug from the cylinder head with a 5/8-
inch spark plug socket.
Tip: Both spark plugs should have the same light or medium tan color
deposits on the insulator around the electrode tip. The spark plug
electrode tip and bridge should have sharp, square edges.
5. If spark plugs are in good condition and are not due for
replacement, clean them with a non-metallic stiff bristle
brush, set the gap with a spark plug gap tool, clean the
mating surface on the cylinder head, and install the spark
plug with a spark plug socket. Reinstall both spark plug wires.
Tip: Spark plugs with bright white or sooty black deposits or with damaged insulators or electrodes can
indicate engine problems. If these conditions exist, or if the condition of one plug is markedly
different from the other, see the
VICTORY Service Manual or your authorized VICTORY dealer.
