For most riding conditions this spark plug heat
range number is satisfactory. However, if the
motorcycle is going to be operated for extended
periods at high speed or near maximum power in
hot climates, the spark plug should be changed
to a colder heat range (a higher number).
1.
Clean any dirt from around the spark plug base.
2. Disconnect the spark plug cap and remove
the spark plug with the spark plug wrench
provided in the tool bag .
3. Visually inspect the spark plug electrodes
for wear. The center electrode should not
be eroded .
Discard the spark plug if there is apparent
wear or if the insulator is cracked or
chipped .
4. Check the spark plug gap (2) using a
wire-type feeler gauge. If adjustment is
necessary , bend the side electrode
(3)
carefully.

The gap should be:
0.80-0.90 mm (0.031-0.035 in)
Make sure the plug washer is in good
condition.
5. With the plug washer attached, thread the
spark plug in by hand to prevent cross-
threading.
6. Ti ghten a new spark plug 1/2 turn with a
spark plug wrench to compress the wash-
er. If you are reusing a plug , it should only
take 1/8-1 /4 turn after the plug seats.
Reinstall the spark plug caps.

• The spark plug must be securely tight-
ened. An improperly tightened plug can
become very hot and possibly damage
the engine.
• Never use a spark plug with an improp-
er heat range. Severe engine damage
could result.
THROTTLE OPERATION
(Refer t o t he maintenance precautions on
page 56).
1.Check for smooth rotation of the throttle
grip from the fully open to the fully closed
position at both full steering positions.
2.
Measure the throttle grip free play at the
throttle grip flange.
The standards free play should be
approx.:
2-6 mm (0.08-0.24 in)
To adjust the free play, loosen the lock
nut (1) and turn the adjuster (2).
