6-PERIODIC MAINTENANCE AND MINOR REPAIR
EAU00464
Periodic inspection, adjustment and lu-
brication will keep your motorcycle in
the safest and most efficient condition
possible. Safety is an obligation of the
motorcycle owner. The maintenance
and lubrication schedule chart should
be considered strictly as a guide to
general maintenance and lubrication
intervals. YOU MUST TAKE INTO
CONSIDERATION THAT WEATHER,
TERRAIN, GEOGRAPHICAL LOCA-
TIONS, AND A VARIETY OF INDIVID-
UAL USES ALL TEND TO DEMAND
THAT EACH OWNER ALTER THIS
TIME SCHEDULE TO SHORTER IN-
TERVALS TO MATCH THE ENVI-
RONMENT. The most important points
of motorcycle inspection, adjustment,
and lubrication are explained in the fol-
lowing pages.

@ If you are not familiar with motor-
cycle service, this work should be
done by a Yamaha dealer. @

Tool kitThe service information included in this
manual is intended to provide you, the
owner, with the necessary information
for completing some of your own pre-
ventive maintenance and minor re-
pairs. The tools provided in the owner’s
tool kit are to assist you in the perfor-
mance of periodic maintenance. How-
ever, some other tools such as a torque
wrench are also necessary to perform
the maintenance correctly.
NOTE:@ If you do not have necessary tools re-
quired during a service operation, take
your motorcycle to a Yamaha dealer for
service. @
EW000063
WARNING
@ Modifications to this motorcycle not
approved by Yamaha may cause
loss of performance, and render it
unsafe for use. Consult a Yamaha
dealer before attempting any chang-
es. @

1. Measure the electrode gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
2. Clean the gasket surface. Wipe off
any grime from the threads.
3. Install the spark plug and tighten it
to the specified torque.
NOTE:@ If a torque wrench is not available when
you are installing a spark plug, a good
estimate of the correct torque is 1/4 to
1/2 turn past finger tight. Have the
spark plug tightened to the specified
torque as soon as possible. @4. Install the spark plug caps.

Engine oilOil level inspection
1. Place the motorcycle on the cen-
terstand. Warm up the engine for
several minutes.NOTE:@ Be sure the motorcycle is positioned
straight up when checking the oil level.
A slight tilt toward the side can result in
false readings. @

the oil level through the level win-
dow located at the lower part of
the right side crankcase cover.
NOTE:@ Wait a few minutes until the oil level
settles before checking. @3. The oil level should be between
the maximum and minimum level
marks. If the level is low, add suffi-
cient oil to raise it to the specified
level.Engine oil and oil filter element re-
placement
1. Warm up the engine for several
minutes.
2. Stop the engine. Place an oil pan
under the engine and remove the
oil filler cap.

cover with the slot in housing and
install the filter cover.

ter drain screw to the specified
torque.
NOTE:@ Make sure the O-rings are seated prop-
erly. @
9. Fill engine with oil. Install the oil fill-
er cap and tighten.

Do not put in any chemical addi-
tives. Engine oil also lubricates

CAUTION:@ Too little chain slack will overload
the engine and other vital parts.
Keep the slack within the specified
limits. @3. After adjusting, tighten the lock-
nuts. Then tighten the axle nut to
the specified torque.
EAU03006
Drive chain lubricationThe chain consists of many parts which
work with each other. If the chain is not
maintained properly, it will wear out
quickly. Therefore, the chain must be
serviced regularly. This service is es-
pecially necessary when riding in dusty
areas. This motorcycle is equipped
with a sealed type chain. Steam clean-
ing, high-pressure washers, and sol-
vents can damage the drive chain, so
do not use these for cleaning it. Use
only kerosene to clean the drive chain.
Wipe it dry, and thoroughly lubricate it
with SAE 30 ~ 50W motor oil. Do not
use any other lubricants on the drive
chain. They may contain solvents that
could damage the sealed chain.
EC000097
CAUTION:@ Be sure to oil the chain after wash-
ing the motorcycle or riding in the
rain. @

Cable inspection and
lubrication
EW000112
WARNING
@ Damage to the outer housing of ca-
bles may lead to internal rusting and
interfere with the cable movement.
Replace damaged cables as soon as
possible to prevent unsafe condi-
tions. @Lubricate the cables and cable ends. If
a cable does not operate smoothly, ask
a Yamaha dealer to replace it. Tightening torque:

Front wheel installation1. Install the speedometer gear unit
housing into the wheel hub. Make
sure the wheel hub and the speed-
ometer gear unit housing are in-
stalled with the projections
meshed into the slots.2. Lift up the wheel between the front
fork legs. Make sure the slot in the
speedometer gear unit housing fits
over the stopper on the front fork
outer tube.
3. Install the wheel axle and let the
motorcycle down.
4. Install the calipers, caliper bolts
and brake hose holders. Make
sure there is enough gap between
the brake pads before installing
the calipers onto the brake discs.5. Tighten the wheel axle, pinch bolt

WARNING
@ l
It is advisable to have a Yamaha
dealer service the wheel.
l
Securely support the motor-
cycle so there is no danger of it
falling over.
@1. Loosen the axle nut and caliper
bolts.
2. Remove the brake torque rod nut
and bolt.3. Place the motorcycle on the cen-
terstand.
4. Remove the axle nut, caliper bolts
and caliper.
5. Loosen the locknuts and chain ad-
justing nuts on each side of the
swingarm.
6. Push the wheel forward and re-
move the drive chain.
7. Support the caliper bracket, pull
out the wheel axle and remove the
wheel assembly by pulling it back-
wards.
NOTE:@ l
Do not depress the brake pedal
when the caliper is off the disc as
the brake pads will be forced shut.

TroubleshootingAlthough Yamaha motorcycles receive
a rigid inspection before shipment from
the factory, trouble may occur during
operation.
Any problem in the fuel, compression,
or ignition systems can cause poor
starting and loss of power. The trouble-
shooting chart describes a quick, easy
procedure for making checks.
If your motorcycle requires any repair,
bring it to a Yamaha dealer. The skilled
technicians at a Yamaha dealership
have the tools, experience, and know-
how to properly service your motor-
cycle. Use only genuine Yamaha parts
on your motorcycle. Imitation parts may
look like Yamaha parts, but they are of-
ten inferior. Consequently, they have a
shorter service life and can lead to ex-
pensive repair bills. Tightening torque:
Axle nut:
150 Nm (15.0 m·kg)
Caliper bolt:
