Spark Plug Service
Recommended spark plugs:
NOTICE
Incorrect spark plugs can cause engine damage.
For good performance, the spark plug [1] must be properly gapped
and free of deposits.
1. Disconnect the spark
plug cap [2], and
remove any dirt from
around the spark plug
area.
2. Remove the spark
plug with a spark plug wrench
[3].
3. Inspect the spark plug.
Replace it if the electrodes
are worn or if the insulator is
cracked or chipped.
4. Measure the spark plug
electrode gap with a suitable
gauge. The gap should be
0.7 ~ 0.8 mm. Correct the
gap, if necessary, by carefully
bending the side electrode.
5. Install the spark plug
carefully, by hand, to avoid
cross-threading.
6. After the spark plug seats,
tighten with a spark plug
wrench to compress the
washer.
If reinstalling the old spark
plug, tighten 1/8 to 1/4 turn
after the spark plug seats.
If installing a new spark plug, tighten 1/2 turn after the spark plug
seats to compress the washer [4].
NOTICE
A loose spark plug can overheat and damage the engine.
Overtightening the spark plug can damage the threads in the
cylinder head.
7. Install the spark plug cap on the spark plug.
