SPARK PLUG CHECK
Recommended Spark Plug: CMR5H (NGK)
The recommended spark plug has the correct heat range
for normal engine operating temperatures.
For good performance, the spark plug must be properly
gapped and free of deposits.
1. Remove the top cover.
Loosen the M5 x 10 hex bolt with a hexagon wrench,
then remove the top cover. (Picture 1)
2. Disconnect the spark plug cap, and remove any dirt from
around the spark plug area (Picture 2).
3. Remove the spark plug with a 5/8-
inch spark plug wrench.
4. Inspect the spark plug. Replace it
if damaged or badly fouled, if the
sealing washer is in poor condition,
or if the electrode is worn.
5. Measure the spark plug electrode
gap with a wire-type feeler gauge.
Correct the gap, if necessary, by
carefully bending the side electrode.
The gap should be:
0.60–.70 mm (0.024–0.028 in)
6. Install the spark plug carefully, by hand, to avoid cross-
threading.
7. After the spark plug is seated, tighten with a 5/8-inch
spark plug wrench to compress the sealing washer.
8. When installing a new spark plug, tighten 1/2 turn after
the spark plug seats to compress the washer.
9. When reinstalling the original spark plug, tighten 1/8–1/4
turn after the spark plug seats to compress the washer.
10. Attach the spark plug cap to the spark plug.
11. Install the top cover, and tighten the M5 x 10 hex bolt
securely with a hexagon wrench.
