CAUTION:_
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 “CD”
grade or higher. In addition, do
not use oils labeled “ENERGY
CONSERVING II” or higher.
Make sure that no foreign mate-
rial enters the crankcase.

check the oil level and correct it if
necessary. Recommended engine oil:

Transfer case oil The transfer case oil level should be
checked before each ride. In addition,
the oil must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
To check the transfer case 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. Remove the oil check bolt, and
then check the oil level in the
transfer case.NOTE:@ The oil should be at the brim of the
check hole. @3. If the oil is below the brim of the
check hole, remove the oil filler
cap, add sufficient oil of the rec-
ommended type to raise it to the
correct level, and then install the
oil filler cap.
4. Install the oil check bolt, and then
tighten it to the specified torque.To change the transfer case oil
1. Place an oil pan under the transfer
case to collect the used oil.
2. Remove the drain bolt and the
check bolt to drain the oil from the
transfer case.
3. Install the drain bolt and the check
bolt, and then tighten the drain bolt
to the specified torque.

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:
When checking the fluid level,
make sure that the top of the brake
fluid reservoir is level.
Use only the recommended quali-
ty brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
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.
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways 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 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 NOTE after the periodic mainte-
nance and lubrication chart. In addition,
have the oil seals of the master cylin-
ders and calipers as well as the brake
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.
Oil seals: Replace every two
years.
Brake hoses: Replace every four
years.

Drive belt slack The drive belt slack should be checked
before each ride and adjusted if neces-
sary.
To check the drive belt slack
1. Place the motorcycle on a level
surface and hold it in an upright
position.
2. Note the current position of the
drive belt using the marks near the
check hole.
NOTE:@ The marks near the drive belt check
hole are 5 mm apart. @3. Note the position of the drive belt
with a force of 45 N (4.5 kgf) ap-
plied to the belt with a belt tension
gauge as shown.
4. Calculate the drive belt slack by
subtracting the measurement not-
ed in step 2 from the measure-
ment noted in step 3.

Checking and lubricating the
cables The operation of all control cables and
the condition of the cables should be

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.

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.

75. Perform the following steps to pro-
tect the cylinders, piston rings, etc.
from corrosion.
a. Remove the spark plug caps and
spark plugs.
b. Pour a teaspoonful of engine oil
into each spark plug bore.
c. Install the spark plug caps onto the
spark plugs, and then place the
spark plugs on the cylinder head
so that the electrodes are ground-
ed. (This will limit sparking during
the next step.)
d. Turn the engine over several times
with the starter. (This will coat the
cylinder walls with oil.)
e. Remove the spark plug caps from
the spark plugs, and then install
the spark plugs and the spark plug
caps.
EWA00003
WARNING
_ To prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turning
the engine over. _
6. Lubricate all control cables and
the pivoting points of all levers and
pedals as well as of the sidestand/
centerstand.
7. Check and, if necessary, correct
the tire air pressure, and then lift
the motorcycle so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
8. Cover the muffler outlets with plas-
tic bags to prevent moisture from
entering them.9. Remove the battery and fully
charge it. Store it in a cool, dry
place and charge it once a month.
Do not store the battery in an ex-
cessively cold or warm place (less
than 0°C or more than 30°C). For
more information on storing the
battery, see page 6-34.
NOTE:_ Make any necessary repairs before
storing the motorcycle. _
