Owner’s tool kit
The owner’s tool kit is located behind
panel A. (See page 6-5 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.

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.

If you are not familiar with motor-
cycle maintenance work, have a
Yamaha dealer do it for you.
NOTE:
If you do not have the tools or experi-
ence required for a particular job,
have a Yamaha dealer perform it for
you.

Modifications not approved by
Yamaha may cause loss of perfor-
mance and render the vehicle
unsafe for use. Consult a Yamaha
dealer before attempting any
changes.

NOTE:
8The annual checks must be performed every year, except if a 6,000 km or 12,000 km maintenance is performed
instead.
8The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
8Hydraulic brake service
8Regularly check and, if necessary, correct the brake fluid level.
8Every two years replace the internal components of the brake master cylinder and caliper, and change the brake
fluid.
8Replace the brake hoses every four years and if cracked or damaged.
*Since these items require special tools, data and technical skills, have a Yamaha dealer perform the service.

Adjusting the engine idling
speed
The engine idling speed must be
checked and, if necessary, adjusted
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.
NOTE:
A diagnostic tachometer is needed to
make this adjustment.
1. Attach the tachometer to the
spark plug lead.
2. Start the engine and warm it up
for several minutes at 1,000–
2,000 r/min while occasionally
revving it to 4,000–5,000 r/min.
NOTE:
The engine is warm when it quickly
responds to the throttle.

8Make sure that the air filter ele-
ment is properly seated in the
air filter case.
8The engine should never be
operated without the air filter
element installed, otherwise
the piston(s) and/or cylinder(s)
may become excessively
worn.
6. Install the air filter case cover by
installing the screws.
7. Install the air filter case by
installing the bolts and tightening
the clamp screw.
EAU00629
Adjusting the carburetor
The carburetor is an important part of
the engine and requires very sophisti-
cated adjustment. Therefore, most
carburetor adjustments should be left
to a Yamaha dealer, who has the
necessary professional knowledge
and experience. The adjustment
described in the following section,
however, may be serviced by the
owner as part of routine mainte-
nance.
EC000094
cC
The carburetor has been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine.

Lubricating the drive chain
The 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
cC
The 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
cC
To prevent damaging the O-rings,
do not clean the drive chain with
steam cleaners, high-pressure
washers or inappropriate solvents.
EC000096
cC
Improper 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 both locknuts, and then
tighten the axle nut to the speci-
fied torque.
4. Adjust the brake pedal free play.
(See page 6-22 for brake pedal
free play adjustment proce-
dures.)

w
After adjusting the brake pedal
free play, check the operation of
the brake light.
Tightening torque:
Axle nut:
104 Nm (10.4 m·kg)
2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant.
ECA00052
cC
Do not use engine oil or any other
lubricants for the drive chain, as
they may contain substances that
could damage the O-rings.

Supporting the motorcycle
Since this model is not equipped with
a centerstand, follow these precau-
tions when removing the front and
rear wheel or performing other main-
tenance requiring the motorcycle to
stand upright. Check that the motor-
cycle is in a stable and level position
before starting any maintenance. A
strong wooden box can be placed
under the engine for added stability.
To service the front wheel
1. Stabilize the rear of the motorcy-
cle by using a motorcycle stand
or, if an additional motorcycle
stand is not available, by placing
a jack under the frame in front of
the rear wheel.
2. Raise the front wheel off the
ground by using a motorcycle
stand.To service the rear wheel
Raise the rear wheel off the ground
by using a motorcycle stand or, if a
motorcycle stand is not available, by
placing a jack either under each side
of the frame in front of the rear wheel
or under each side of the swingarm.

Troubleshooting
Although 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:
104 Nm (10.4 m·kg)

Be sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled “Energy
Conserving”) contain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting in reduced
component life and poor engine performance.
