To install the spark plug

1. Measure the spark plug gap with a

wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.

2. Clean the surface of the spark plug

gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.

3. Install the spark plug with the

spark plug wrench, and then tight-
en it to the specified torque.

TIP

If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-

fied torque as soon as possible.

4. Install the spark plug cap.

TIP

Make sure the spark plug wire is fas-

tened in the clamp as shown.

5. Install the spark plug cover by in-

stalling the screws.

6. Place the storage compartment

mat in the original position.

7. Close the rider seat.
