If replacing with any other brand of spark plug, be cer-
tain to select the correct reach and heat range. Before
removing the spark plug, clean the spark plug area thor-
oughly to prevent dirt from entering the cylinder.
CAUTION:
•
The use of a spark plug of the incorrect reach or
heat range can cause engine damage. The use of a
non-resistor spark plug may cause ignition prob-
lems.
This motorcycle uses spark plug that have an iridium
tip in center electrode and a platinum tip in side elec-
trode .
Be sure to observe the following when servicing the
spark plug.
•
Do not clean the spark plug. If an electrode is con-
taminated with accumulated objects or dirt, replace
the spark plug with a new one.
•
Use only a “wire-type feeler gauge” to check the
spark plug if necessary. To prevent damaging the
iridium tip of the center electrode and platinum tip
of the side electrode, never use a leaf-type feeler
gauge.

4. Check the electrode for wear or deposits, the gasket
for damage, and the insulator for cracks. Replace if
you detect them.
5. Check the spark plug gap, using a wire-type feeler
gauge. If the gap is out of specifications, replace the
plug with a new one.
The recommended spark plug gap is:
0.039 – 0.043 in (1.0 – 1.1 mm)
