Spark Plugs
Spark Plug Inspection
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 Ser-
vice Manual or your authorized VICTORY dealer.
