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
several 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-left side of the crank-
case.
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 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.
3. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.1. Engine oil level check window

69. Add the specified amount of the
recommended oil, and then install
and tighten the oil filler 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.
_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.
11. Turn the engine off, and then
check the oil level and correct it if
necessary.

Final gear oil The final gear case must be checked
for oil leakage before each ride. If any
leakage is found, have a Yamaha deal-
er check and repair the motorcycle. In
addition, the final gear oil level must be
checked and the oil changed as follows
at the intervals specified in the periodic
maintenance and lubrication chart.

WARNING
@ l
Make sure that no foreign mate-
rial enters the final gear case.
l
Make sure that no oil gets on
the tire or wheel.
@To check the final gear oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position. Recommended engine oil:
See page 8-1.
Oil quantity:
Without oil filter element
replacement:
2.6 L

NOTE:@ l
The final gear oil level must be
checked on a cold engine.
l
Make sure that the motorcycle is
positioned straight up when
checking the oil level. A slight tilt to
the side can result in a false read-
ing.
@2. Remove the oil filler bolt, and then
check the oil level in the final gear
case.
NOTE:@ The oil level should be at the brim of
the filler hole. @3. If the oil is below the brim of the fill-
er hole, add sufficient oil of the rec-
ommended type to raise it to the
correct level.
To change the final gear oil
1. Place an oil pan under the final
gear case to collect the used oil.
2. Remove the oil filler bolt and drain
bolt to drain the oil from the final
gear case.
3. Install the final gear oil drain bolt,
and then tighten it to the specified
torque.
4. Add the recommended final gear
oil to the brim of the filler hole.
NOTE:@ GL4 is a quality rating. Hypoid gear oils
rated GL5 or GL6 may also be used. @5. Install and tighten the filler bolt to
the specified torque.
6. Check the final gear case for oil
leakage. If oil is leaking, check for
the cause.

Checking the brake fluid level Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it to become ineffective.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake flu-
id level may indicate worn brake pads
and/or brake system leakage. If the
brake level is low, be sure to check the
brake pads for wear and the brake sys-
tem for leakage.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.

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.

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. @
EAU03764
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. Hold up the throttle cable, and
then apply several drops of oil to
the cable, allowing it to trickle into
the sheaths.
3. Grease the inside of the throttle
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:
