TIP
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4–1/2 turn past finger tight. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.

Engine oil
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
service indicator light comes on.
To check the engine oil level
1. Place the scooter on the centers-
tand. 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 (wit-
hout screwing it in), and then
remove it again to check the oil
level.
TIP
The engine oil should be between the
minimum and maximum level marks.
1. Engine oil filler cap
2. Maximum level mark
3. Minimum level mark
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 (with or
without oil filter element
replacement)
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.

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.

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.
13. Turn the engine off, and then
check the oil level and correct it if
necessary.
14. Reset the oil change indicator.

TIP
If the engine oil is changed before the
oil change indicator comes on (i.e.
before the periodic oil change interval
has been reached), the indicator must
be reset after the oil change for the
next periodic oil change to be indica-
ted at the correct time. To reset the oil
change indicator before the periodic
oil change interval has been reached,
follow the above procedure, but note
that the indicator will come on for 1.4
seconds after releasing the “OIL
CHANGE” button, otherwise repeat
the procedure.EAU20065
Final transmission oil
The final transmission case must be
checked for oil leakage before each
ride. If any leakage is found, have a

periodic maintenance and lubrication
chart.
1. Start the engine, warm up the
final transmission oil by riding the
scooter for several minutes, and
then stop the engine.
2. Place the scooter on the centers-
tand.
3. Place an oil pan under the final
transmission case to collect the
used oil.
4. Remove the final transmission oil
filler cap and its O-ring from the
final transmission case.
5. Remove the final transmission oil
drain bolt and its gasket to drain
the oil from the final transmission
case.

Coolant
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.
EAUS1670
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
TIP
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.
2. Check the coolant level through
the check window.
TIP
The coolant should be between the
minimum and maximum level marks.
1. Maximum level mark
2. Minimum level mark
3. Coolant level check window
3. If the coolant is at or below the
minimum level mark, lift up the
right floorboard mat as shown.

Be careful that water or dust
does not enter the brake fluid
reservoir when refilling. Water will
significantly lower the boiling
point of the fluid and may result
in vapor lock, and dirt may clog
the ABS hydraulic unit valves.
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.
EAU22731
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenan-
ce 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.
EAU23112
Checking and lubricating the
throttle grip and cable
The operation of the throttle grip
should be checked before each ride.
In addition, the cable should be lubri-
cated by a Yamaha dealer at the inter-
vals specified in the periodic mainte-
nance chart.

each ride, and the pivots and metal-
to-metal contact surfaces should be
lubricated if necessary.
EWA10741
If the centerstand or sidestand
does not move up and down smo-
othly, have a Yamaha dealer check
or repair it. Otherwise, the centers-
tand or sidestand could contact the
ground and distract the operator,
resulting in a possible loss of con-
trol.
EAU23272
Checking the front fork
The condition and operation of the
front fork must be checked as follows
at the intervals specified in the perio-
dic maintenance and lubrication
chart.
To check the condition
1. Check the inner tubes for scrat-
ches, damage and excessive oil
leakage.
To check the operation
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion. WARNING! To avoid injury,
securely support the vehicle so
there is no danger of it falling
over.
[EWA10751]
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.
ECA10590
If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or
repair it.

fuel from deteriorating.
3. Perform the following steps to
protect the cylinder, piston rings,
etc. from corrosion.
a. Remove the spark plug cap
and spark plug.
b. Pour a teaspoonful of engine
oil into the spark plug bore.
c. Install the spark plug cap
onto the spark plug, and then
place the spark plug on the
cylinder head so that the
electrodes are grounded.
(This will limit sparking during
the next step.)
d. Turn the engine over several
times with the starter. (This
will coat the cylinder wall with
oil.)
e. Remove the spark plug cap
from the spark plug, and then
install the spark plug and the
spark plug cap. WARNING!
To prevent damage or injury
from sparking, make sure
to ground the spark plug
electrodes while turning the
engine over.
[EWA10951]
4. Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
5. Check and, if necessary, correct
the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground. Alter-
natively, turn the wheels a little
every month in order to prevent
the tires from becoming degra-
ded in one spot.
6. Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.
7. 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 excessively cold or warm pla-
ce [less than 0 °C (30 °F) or more
than 30 °C (90 °F)]. For more
information on storing the bat-
tery, see page 6-26.
TIP
Make any necessary repairs before
storing the scooter.
