PERIODIC MAINTENANCE AND MINOR REPAIR

2. Remove the spark plug as

shown, with the spark plug
wrench included in the owner’s
tool kit.

To check the spark plug

1. Check that the porcelain insula-

tor around the center electrode
of the spark plug is a medium-to-
light tan (the ideal color when the
motorcycle is ridden normally).

NOTE:
If the spark plug shows a distinctly
different color, the engine could be
defective. Do not attempt to diagnose
such problems yourself. Instead,
have a Yamaha dealer check the
motorcycle.

2. Check the spark plug for elec-

trode erosion and excessive car-
bon or other deposits, and
replace it if necessary.

To install the spark plug

1. Measure the spark plug gap with

a wire thickness gauge and, if
necessary, adjust the gap to
specification.

2. Clean the surface of the spark

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

3. Install the spark plug with the

spark plug wrench, and then
tighten it to the specified torque.

Spark plug wrench

Spark plug gap

Spark plug gap:

0.7–0.8 mm

Specified spark plug:

CR9E (NGK) or
U27ESR-N (DENSO)
