Measure the spark plug gap with a wire thick-
ness gauge and, if necessary, adjust the gap
to specification.a. Spark plug gap
Installation 1. Clean the surface of the spark plug gas- ket and its mating surface, and then wipe
off any grime from the spark plug
threads.
2. Install the spark plug and tighten it to the
specified torque. If a torque wrench is not
available when you are installing the
spark plug, a good estimate of the correct
torque is one-quarter to one-half turn
past finger tight. Have the spark plug
tightened to the specified torque as soon
as possible.
3. Install the spark plug cap.
4. Lower the cargo bed.
Spark plug gap:
0.8–0.9 mm (0.031–0.035 in)
Tightening torque:Spark plug: 13 Nm (1.3 m·kgf, 9.4 ft·lbf)

holes.
5. Install the bolts and tighten them to the specified torque.
Valve clearanceThe correct valve clearance changes with
use, resulting in improper fuel/air supply or
engine noise. To prevent this, the valve clear-
ance must be adjusted regularly. This adjust-
ment however, should be left to a professional
Yamaha service technician.

Viking to widen the track width. Installing
wheels improperly increases the risk of
wheel failure and accidents.

water. However, the battery lead connections
need to be checked and, if necessary, tight-
ened.
