Engine oil and oil filter
cartridge The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_ Make sure that the motorcycle is posi-
tioned straight up when checking the oil
level. A slight tilt to the side can result in
a false reading. _
2. Start the engine, warm it up for sev-
eral minutes, and then turn it off.
3. Wait a few minutes until the oil set-
tles, and then check the oil level
through the check window located
at the bottom-right side of the
crankcase.NOTE:_ The engine oil should be between the
minimum and maximum level marks. _4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.To change the engine oil (with or
without oil filter cartridge replace-
ment)
1. Remove cowling A. (See page 6-5
for cowling removal and installa-
tion procedures.)
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Place an oil pan under the engine
to collect the used oil.1. Engine oil level check window

64. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.
NOTE:_ Skip steps 5–7 if the oil filter cartridge is
not being replaced. _
5. Remove the oil filter cartridge with
an oil filter wrench.NOTE:_ An oil filter wrench is available at a
Yamaha dealer. _
6. Apply a thin coat of engine oil to
the O-ring of the new oil filter car-
tridge.NOTE:_ Make sure that the O-ring is properly
seated. _7. Install the new oil filter cartridge,
and then tighten it to the specified
torque with a torque wrench.

then tighten it to the specified
torque.
9. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil filler
cap.

CAUTION:_ l
In 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 a higher
grade than “CD”. In addition, do
not use oils labeled “ENERGY
CONSERVING II” or higher.
l
Make sure that no foreign mate-
rial enters the crankcase.
_
10. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.NOTE:_ After the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient. _
EC000067
CAUTION:_ If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha deal-
er check the vehicle. _11. Turn the engine off, and then
check the oil level and correct it if
necessary.

to the entire surface of the sponge
material, and then squeeze the ex-
cess oil out.
NOTE:_ The air filter element should be wet but
not dripping. _8. Insert the air filter element into the
air filter case.
EC000082
CAUTION:_ l
Make sure that the air filter ele-
ment is properly seated in the
air filter case.
l
The engine should never be op-
erated without the air filter ele-
ment installed, otherwise the
piston(s) and/or cylinder(s) may
become excessively worn.
_9. Install the air filter case cover by
installing the screws.
10. Place the fuel tank in the original
position, and then install the bolts.

WARNING
_ Make sure that the fuel hoses and
vacuum hose are properly connect-
ed and routed, and not pinched. Re-
place any damaged hoses. _11. Install the seat.
EAU00626
Checking the air vent hose Periodically check the air vent hose for
dust or water that may be deposited in
the hose. If dust or water is found, re-
move the air vent hose, thoroughly
clean it, and then install it.

CAUTION:_ Do not operate the motorcycle with
the air vent hose removed. _

6 Observe these precautions:
l
When checking the fluid level,
make sure that the top of the brake
fluid reservoir is level.
l
Use only the recommended quali-
ty brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
l
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
l
Be careful that water does not en-
ter the brake fluid reservoir when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
EAU03238
Changing the brake fluid Have a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil seals
of the brake master cylinder and caliper
as well as the brake hose replaced at
the intervals listed below or whenever
they are damaged or leaking.l
Oil seals: Replace every two
years.
l
Brake hose: Replace every four
years.

NOTE:_ Using the alignment marks on each
side of the swingarm, make sure that
both adjusting nuts are in the same po-
sition for proper wheel alignment. _
EC000096
CAUTION:_ Improper drive chain slack will over-
load 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 locknuts, and then
tighten the axle nut to the specified
torque.
EAU03006
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
CAUTION:_ The drive chain must be lubricated
after washing the motorcycle or
riding in the rain. _1. Clean the drive chain with kero-
sene and a small soft brush.
ECA00053
CAUTION:_ To prevent damaging the O-rings,
do not clean the drive chain with
steam cleaners, high-pressure
washers or inappropriate solvents. _2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant.
ECA00052
CAUTION:_ Do not use engine oil or any other
lubricants for the drive chain, as
they may contain substances that
could damage the O-rings. _

Checking and lubricating the
cables The operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubricat-
ed if necessary. If a cable is damaged
or does not move smoothly, have a
Yamaha dealer check or replace it.
EW000112
WARNING
_ Damage to the outer sheath may in-
terfere with proper cable operation
and will cause the inner cable to
rust. Replace a damaged cable as
soon as possible to prevent unsafe
conditions. _
EAU03209
Checking and lubricating the
throttle grip and cable The operation of the throttle grip and
the condition of the throttle cable
should be checked before each ride,
and the cable should be lubricated or
replaced if necessary.NOTE:_ Since the throttle grip must be removed
to access the throttle cable end, the
throttle grip and the cable should al-
ways be lubricated at the same time. _1. Remove the throttle grip by remov-
ing the screws.
2. Disconnect the throttle cable, hold
it up, and then apply several drops
of oil to the cable end, allowing it to
trickle into the sheath.
3. Connect the throttle cable, and
then grease the inside of the throt-
tle grip housing.
4. Grease the metal-to-metal contact
surface of the throttle grip, and
then install the grip by installing
the screws. Recommended lubricant:
Engine oil
Recommended lubricant:
Throttle cable:

WARNING
_ Securely support the motorcycle so
that there is no danger of it falling
over. _Check the inner tubes for scratches,
damage and excessive oil leakage.To check the operation
1. Place the motorcycle on a level
surface and hold it in an upright
position.
2. While applying the front brake,
push down hard on the handle-
bars several times to check if the
front fork compresses and re-
bounds smoothly.
EC000098
CAUTION:_ If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or re-
pair it. _
Recommended lubricant:
