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 differ-
ent from the other, see the VICTORY Service Manual or your authorized VICTORY dealer.
