Spark Plugs

For nickel spark plugs (traditional type):
You should inspect spark plugs periodically
for carbon deposits. When carbon accu-
mulates on a spark plug, a strong spark
may not be produced. Remove carbon
deposits with a wire or pin and adjust the
spark plug gap.
To access the spark plugs:
1) Unclamp and remove the air cleaner
case.
2) If necessary, disconnect the coupler (1)
while pushing the release lever.
3) Remove the ignitor bolts.
4) Pull the spark plug boots out.
NOTE:
When installation, make sure the wires,
couplers, sealing rubber of top cover and
washers, are correctly returned in place.

CAUTION
• When disconnecting the spark plug
cables, pull on the boot, not on the
cable itself. Pulling on the cable
can damage it.
• When servicing the iridium/plati-
num spark plugs (slender center
electrode type plugs), do not touch
the center electrode, as it is easy to
damage.
