Differential gear oil
Checking the differential gear oil level
1. Park the vehicle on a level surface.
2. Remove the differential gear oil filler bolt and
check the oil level. It should be up to the brim
of the filler hole. If the level is low, add suffi-
cient oil of the recommended type to raise it
to the specified level. NOTICE: Be sure no
foreign material enters the differential
gear case.
3. Reinstall the differential gear oil filler bolt, and
then tighten it to the specified torque.

3. Place a container under the differential gear
case to collect the used oil.
4. Remove the differential gear oil filler bolt and
differential gear oil drain bolt to drain the oil.
5. Reinstall the differential gear oil drain bolt,
and tighten it to the specified torque.

Installation
1. Measure the electrode gap with a wire thick-
ness gauge and, if necessary, adjust the gap
to specification.
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 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 speci-
fied torque as soon as possible.
4. Install the spark plug cap.
5. Reinstall the console.Spark plug gap:
0.8–0.9 mm (0.031–0.035 in)
Tightening torque:
Spark plug:
12.5 Nm (1.25 m·kgf, 9.0 ft·lbf)

Cleaning the spark arrester
WARNING
Hot exhaust system may cause burns. To
avoid burns or fires, make sure that the engine
is stopped and the exhaust system is cool be-
fore cleaning spark arrester. Do not start the
engine while cleaning the exhaust system.1. Remove the bolts.
2. Remove the tailpipe by pulling it out of the
muffler, and then remove the gasket.
3. Tap the tailpipe lightly, and then use a wire
brush to remove any carbon deposits from
the spark arrester portion of the tailpipe and
inside of the tailpipe housing.
4. Install the gasket, and then insert the tailpipe
into the muffler and align the bolt holes.
5. Install the bolts and tighten them to the spec-
ified torque.

Valve clearance
The correct valve clearance changes with use, re-
sulting in improper fuel/air supply or engine noise.
To prevent this, the valve clearance must be ad-
justed regularly. This adjustment however, should
be left to a professional Yamaha service techni-
cian.Tightening torque:
Tailpipe bolt:
