Spark Plug Service
For good performance, the spark plug must be properly gapped and free of deposits.

Disconnect the spark plug cap and remove any dirt from around the spark plug area.

Remove the spark plug with a spark plug wrench.

Inspect the spark plug. Replace it if the electrodes are worn, or if the insulator is
cracked or chipped.

Measure the spark plug electrode gap with a suitable gauge. The gap should be
0.028 ~ 0.031 in (0.7 ~ 0.8mm). Correct the gap, if
necessary, by carefully bending the side electrode with a
suitable tool.

Install the spark plug carefully, by hand, to avoid
cross-threading.

Install the spark plug cap on the spark plug.
