INSPECTION AND MAINTENANCE
Replacing the spark plugs
 Do not reuse spark plug with damaged
insulation, or sparks can leak through
crack, potentially leading to electric
shock, explosion and/or fire.
 Do not touch spark plugs immediately
after stopping engine as they will be hot
and could
touched. Allow motor to cool down first.
Note
When inspecting the plug, always clean the
gasket surface and use a new gasket. Wipe
off any dirt from the threads and screw in
the spark plug to the correct torque.
If the spark plug(s) is fouled, has carbon
build up, or is worn, it should be replaced.
When reusing spark plugs, remove dirt
from the electrodes and adjust spark gap
to specification.
1
Remove the top cowl.
2
Remove the spark plugs by turning
counter-clockwise
wrench (21 mm: 13/16 in) fitted with the
handle. Tap lightly on the spark plugs if
9
they are hard to turn.
WARNING
cause severe burns
with the socket
Use spark plug NGK B8HS-10.
Spark gap : 0.9 - 1.0mm
Notes
if
 Spark plug torque :
27.0Nm (20ft-lb) (2.7kgf-m)
If a torque-wrench is not available when you
are fitting a spark plug, a good estimate of
the correct torque is 1/4 to
1/2 a turn past finger-tight. Have the spark
plug adjusted to the correct torque as soon
as possible with a torque-wrench.
Do not touch the high tension cords run-
ning from the ignition coil to the spark
plugs while the engine is running or is
turned by the electric starter motor, not
even for testing the high tension cords or
the spark plugs.
The high tension cords and the spark plugs
generate very high electric voltage, which
can cause a serious electric shock if
touched.
