wThis shock absorber contains
highly pressurized nitrogen gas.
For proper handling, read and
understand the following informa-
tion before handling the shock
absorber. The manufacturer can-
not be held responsible for proper-
ty damage or personal injury that
may result from improper han-
dling.
8Do not tamper with or attempt
to open the gas cylinder.
8Do not subject the shock
absorber to an open flame or
other high heat sources, other-
wise it may explode due to
excessive gas pressure.
8Do not deform or damage the
gas cylinder in any way, as
this will result in poor damp-
ing performance.
8Always have a Yamaha dealer
service the shock absorber.

SidestandSidestandThe sidestand is located on the left
side of the frame. Raise the side-
stand or lower it with your foot while
holding the motorcycle upright.NOTE:
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situ-
ations. (See further down for an
explanation of the ignition circuit cut-
off system.)

Owner’s tool kitTool kitThe owner’s tool kit is located behind
panel A. (See page 6-7 for panel
removal and installation procedures.)
The service information included in
this manual and the tools provided in
the owner’s tool kit are intended to
assist you in the performance of pre-
ventive maintenance and minor
repairs. However, additional tools
such as a torque wrench may be nec-
essary to perform certain mainte-
nance work correctly.

wIf you are not familiar with motor-
cycle maintenance work, have a
Yamaha dealer do it for you.

Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. The most important
points of inspection, adjustment, and
lubrication are explained on the fol-
lowing pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, DEPENDING
ON THE WEATHER, TERRAIN,
GEOGRAPHICAL LOCATION, AND
INDIVIDUAL USE, THE MAINTE-
NANCE INTERVALS MAY NEED TO
BE SHORTENED.

6To 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.3. Install the spark plug with the
spark plug wrench, and then
tighten it to the specified torque.
NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4-
1/2 turn past finger tight. However,
the spark plug should be tightened to
the specified torque as soon as pos-
sible.4. Install the spark plug cap. 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.

element.
7. Check the O-rings for damage
and replace them if necessary.
8. Install the oil filter element cover
by installing the bolts, then tight-
ening them to the specified
torque.
NOTE:
Make sure that the O-ring is properly
seated.9. Install the engine oil drain bolts,
and then tighten them to the
specified torques.
10. Add the specified amount of the
recommended engine oil, install
and tighten the oil filler cap, and
then install the oil filler cap cover.
ECA00105
cC8In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives
with the oil or use oils of grade
“CD” or higher. In addition, do
not use oils labeled “ENERGY
CONSERVING II” or higher.
8Make sure that no foreign
material enters the crankcase.

are in the same position for proper
wheel alignment.

cCImproper drive chain slack will
overload the engine as well as
other vital parts of the motorcycle
and can lead to chain slippage or
breakage. To prevent this from
occurring, keep the drive chain
slack within the specified limits.3. Tighten the axle nut and the
brake caliper bracket bolt to the
specified torques.2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant.
ECA00052
cCDo not use engine oil or any other
lubricants for the drive chain, as
they may contain substances that
could damage the O-rings.
EAU03006
Lubricating the drive chainDrive chain, lubricatingThe drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly
wear out, especially when riding in
dusty or wet areas. Service the drive
chain as follows.
EC000097
cCThe drive chain must be lubricated
after washing the motorcycle or
riding in the rain.1. Clean the drive chain with
kerosene and a small soft brush.
ECA00053
cCTo prevent damaging the O-rings,
do not clean the drive chain with
steam cleaners, high-pressure
washers or inappropriate solvents.

NOTE:
Make sure that there is enough
space between the brake pads
before inserting the brake disc and
that the slot in the speedometer gear
unit fits over the retainer on the fork
leg.3. Install the wheel axle.
4. Lower the front wheel so that it is
on the ground.
5. Tighten the wheel axle to the
specified torque.7. After tightening the holder nuts,
while applying the front brake,
push down on the handlebars
several times to check if the front
fork compresses and rebounds
smoothly.
8. Connect the speedometer cable.

then remove the drive chain from
the rear sprocket.
NOTE:
The drive chain does not need to be
disassembled in order to remove and
install the wheel.7. Pull the wheel axle out, and then
remove the wheel.
ECA00048
cCDo not apply the brake after the
wheel has been removed together
with the brake disc, otherwise the
brake pads will be forced shut.

To install the rear wheelInstall1. Install the drive chain onto the
rear sprocket, and then insert the
wheel axle from the left-hand
side.NOTE:
8Make sure that there is enough
space between the brake pads
before inserting the brake disc
between the brake pads.
8Make sure that the drive chain
adjusting plates are installed with
the punched sides facing to the
outside.2. Install the swingarm end bolts.
3. Adjust the drive chain slack.
(See page 6-25 for drive chain
slack adjustment procedures.)

TroubleshootingTroubleshootingAlthough Yamaha motorcycles
receive a thorough inspection before
shipment from the factory, trouble
may occur during operation. Any
problem in the fuel, compression, or
ignition systems, for example, can
cause poor starting and loss of
power.
The following troubleshooting chart
represents a quick and easy proce-
dure for checking these vital systems
yourself. However, should your
motorcycle require any repair, take it
to a Yamaha dealer, whose skilled
technicians have the necessary tools,
experience, and know-how to service
the motorcycle properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life
and can lead to expensive repair
bills. Tightening torque:
Axle nut:
105 Nm (10.5 m0kgf)
Brake caliper bracket bolt:
48 Nm (4.8 m0kgf)
Swingarm end bolt:
2.5 Nm (0.25 m0kgf)
