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 the air cleaner cover.
2) Remove the engine top cover.
3) If necessary, disconnect the coupler (1)
while pushing the release lever.
4) Remove the igniter bolts.5) Pull the
spark plug boots out.

couplers, sealing rubber of top cover and
washers, are correctly returned in place.

NOTICE
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.
NOTICE
When installing the spark plugs,
screw them in with your fingers to
avoid stripping the threads.
Tighten with a torque wrench to
17.5 Nm (1.8 kg-m, 12.916 lb-ft). Do
not allow contaminants to enter the
engine through the spark plug
holes when the plugs are removed.
Never use spark plugs with the
wrong thread size.
NOTICE
When replacing spark plugs, you
should use the brand and type speci-
fied for your vehicle. For the speci-
fied spark plugs, refer to the
“SPECIFICATIONS” section at the
end of this book. If you wish to use a
