Engine oil and oil filter
element The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation 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
15 minutes, and then turn it off.3. Check the oil level through the
check window located on the right
side of the engine oil tank.
NOTE:@ l
The engine oil tank is located be-
hind the cylinders.
l
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 element replace-
ment)
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the engine
to collect the used oil.1. Engine oil level check window

68. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil tank
cap.
EC000072
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.
@9. 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.
10. Turn the engine off, and then
check the oil level and correct it if
necessary.
EAU03495
Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
If the engine overheats, see page 6-45
for further instructions.
To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:@ l
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
l
Make sure that the motorcycle is
positioned straight up when
checking the coolant level. A slight
tilt to the side can result in a false
reading.

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.

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. @
EAU02962
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. @
Recommended lubricant:

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.
EAU03370
Checking and lubricating the
brake and shift pedals The operation of the brake and shift
pedals should be checked before each
ride, and the pedal pivots should be lu-
bricated if necessary. Recommended lubricant:
Throttle cable:
Engine oil
Throttle grip housing and grip:
Lithium-soap-based grease
(all-purpose grease) Recommended lubricant:
Lithium-soap-based grease

Lubricating the rear
suspension The pivoting points of the rear suspen-
sion must be lubricated at the intervals
specified in the periodic maintenance
and lubrication chart.

Checking the front fork The condition and operation of the front
fork must be checked as follows at the
intervals specified in the periodic main-
tenance and lubrication chart.
To check the condition
EW000115
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:
Molybdenum disulfide grease
