Engine oil
1. Dipstick
(a) Maximum level (b) Minimum level
The engine oil level should be chec-
ked before each ride. In addition, the
oil must be changed at the intervals
specified in the periodic maintenance
and lubrication chart and when the oil
change indicator light comes on.
To check the engine oil level
1. Place the vehicle on the centers-
tand.
NOTE:
Make sure that the vehicle is positio-
ned 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
settles, remove the oil filler cap,
wipe the dipstick clean, insert it
back into the oil filler hole (without
screwing it in), and then remove it
again to check the oil level.
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 rai-
se it to the correct level.
5. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.To change the engine oil
1. Drainage cap
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 the engine oil drain bolt to
drain the oil from the crankcase.
ECA10410
CAUTION
When removing the engine oil drain
bolt, the O-ring, spring, and oil
strainer will fall out. Take care not
to lose these parts.

CAUTION
Do not use oils with a diesel
specification of “CD” or oils of
a higher quality than specified.
In addition, do not use oils
labeled “ENERGY CONSER-
VING II” or higher.
Be sure no foreign material
enters the crankcase.
8. 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 cau-
se.
9. Reset the oil change indicator
light according to the following
procedure.To reset the oil change indicator
light
1. Push and hold the “TRIP” button
for a MAXIMUM of three
seconds. While pushing the
“TRIP” button, turn the key to
“f”.
2. Release the “TRIP” button and
the oil change indicator light will
go off.
3. Turn the key to “e”.
NOTE:
If the engine oil is changed before the
oil change indicator light comes on
(i.e. before the periodic oil change
interval has been reached), the indi-
cator light must be reset after the oil
change for the next periodic oil chan-
ge to be indicated at the correct time.
To reset the oil change indicator light
before the periodic oil change interval
has been reached, follow the above
procedure, but note that the indicator
light will come on for 1.4 seconds
after releasing the reset button, other-
wise repeat the procedure.

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

WARNING
Make sure that no foreign
material enters the final gear
case.
Make sure that no oil gets on
the tire or wheel.
To check the final gear oil level
1. Place the vehicle on the centers-
tand.
1. Drain bolt
NOTE:
The final gear oil level must be
checked on a cold engine.
Make sure that the vehicle is posi-
tioned straight up when checking
the oil level. A slight tilt to the side
can result in a false reading.
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
filler hole, add sufficient oil of the
recommended type to raise it to
the correct level.
4. Install the oil filler bolt, and then
tighten it to the specified torque.
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.

Coolant
1. Maximum level
2. Minimum level
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUS1080
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
NOTE:
The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
Make sure that the vehicle is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
1. Coolant tank cap
2. Check the coolant level through
the check window.
NOTE:
The coolant should be between the
minimum and maximum level marks.

3. If the coolant is at or below the
minimum level mark, remove the
front cowling by removing the
screws.
4. Open the reservoir cap, and then
add coolant to the maximum
level mark.
ECA10470
CAUTION
If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.
If water has been used instead
of coolant, replace it with coo-
lant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the coo-
ling system will not be protec-
ted against frost and corrosion.
If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possi-
ble, otherwise the effective-
ness of the coolant will be
reduced.
5. Close the reservoir cap, and then
install the front cowling by insta-
lling the screws.

Adjusting the carburetor
The carburetor is an important part of
the engine and requires very sophisti-
cated adjustment. Therefore, all car-
buretor adjustments should be left to
a Yamaha dealer, who has the neces-
sary professional knowledge and
experience.
EAU21381

Observe these precautions:
When checking the fluid level,
make sure that the top of the bra-
ke fluid reservoir is level.
Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.
Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
Brake fluid may deteriorate pain-
ted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
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
suddenly, have a Yamaha dealer
check the cause.
EAUM1360
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 brake
hose replaced every four years or
whenever it is damaged or leaking.
EAU23100
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 cables and cable ends should
be lubricated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or repla-
ce it.
EWA10720

WARNING
Damage to the outer sheath may
interfere with proper cable opera-
tion and will cause the inner cable
to rust. Replace a damaged cable
as soon as possible to prevent
unsafe conditions.

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
rebounds smoothly.

CAUTION
If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or
repair it.
EAU23280
Checking the steering
Worn or loose steering bearings may
cause danger. Therefore, the opera-
tion of the steering must be checked
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.
1. Place a stand under the engine to
raise the front wheel off the
ground.
Recommended lubricant:
