1. Socket wrench
4. Remove the spark plugs by turning it
counter-clockwise, using a 13/16" (21
mm) socket wrench and handle that is
provided in tool bag.
5. Inspect the spark plug. Replace the
spark plug if the electrodes are worn
or if the insulators are cracked or
chipped.
6. Measure the spark plug electrode gap
with a wire type feeler gauge. The gap
should be 0.9-1.0 mm (0.035-0.039
inches). If the gap is different, replace
the spark plug with a new one
Use spark plug (NGK BP6HS-10 or
BPR6HS-10) or recommended ones.
1. Electrode
2. Spark gap (0.9–1.0 mm, 0.035–0.039 in)
7. Install the spark plug by hand and turn
it carefully to avoid cross-threading.
8. Tighten the spark plug to the speci-
fied torque.

Note
z Spark plug torque:
27.0 Nm (20.0 ft-lb) [2.7 kgf-m]
If a torque-wrench is not available when
you are fitting a spark plug, a good esti-
mate 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.
