Checking the wheel bearings
The front and rear wheel bearings
must be checked at the intervals spe-
cified in the periodic maintenance and
lubrication chart. If there is play in the
wheel hub or if the wheel does not
turn smoothly, have a Yamaha dealer
check the wheel bearings.

2. Positive battery terminal
3. Negative battery terminal
A poorly maintained battery will
corrode and discharge quickly. The
electrolyte level, battery lead connec-
tions and breather hose routing
should be checked before each ride
and at the intervals specified in the
periodic maintenance and lubrication
chart.
To check the electrolyte level
1. Place the scooter on a level sur-
face and hold it in an upright
position.
TIP
Make sure that the scooter is positio-
ned straight up when checking the
electrolyte level.
2. Remove panel B. (See page 6-7).
3. Check the electrolyte level in the
battery.
1. Maximum level mark
2. Minimum level mark
TIP
The electrolyte should be between
the minimum and maximum level
marks.
4. If the electrolyte is at or below the
minimum level mark, add distilled
water to raise it to the maximum
level mark. NOTICE: Use only
distilled water, as tap water

WARNING
●Electrolyte is poisonous and
dangerous since it contains
sulfuric acid, which causes
severe burns. Avoid any con-
tact with skin, eyes or clothing
and always shield your eyes
when working near batteries.
In case of contact, administer
the following FIRST AID.
• EXTERNAL: Flush with plenty
of water.
• INTERNAL: Drink large quan-
tities of water or milk and
immediately call a physician.
• EYES: Flush with water for 15
minutes and seek prompt
medical attention.
●Batteries produce explosive
hydrogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed spa-
ce.
●KEEP THIS AND ALL BATTE-
RIES OUT OF THE REACH OF
CHILDREN.
5. Check and, if necessary, tighten
the battery lead connections and
correct the breather hose routing.
To store the battery
1. If the scooter will not be used for
more than one month, remove
the battery, fully charge it, and
then place it in a cool, dry place.
NOTICE: When removing the
battery, be sure the key is tur-
ned to “ ”, then disconnect
the negative lead before dis-
connecting the positive lead.
[ECA16302]
2. If the battery will be stored for
more than two months, check the
specific gravity of the electrolyte
at least once a month and fully
charge the battery whenever
necessary.
3. Fully charge the battery before
installation.4. After installation, make sure that
the battery leads are properly
connected to the battery termi-
nals and that the breather hose is
properly routed, in good condi-
tion, and not obstructed. NOTI-
CE: If the breather hose is posi-
tioned in such a way that the
frame is exposed to electrolyte
or gas expelled from the bat-
tery, the frame could suffer
structural and external dama-
ges.

Starting problems or poor engine performance
Check the fuel level in
the fuel tank.
1. FuelThere is enough fuel.
There is no fuel.Check the compression.
Supply fuel.
Operate the electric starter.
2. CompressionThere is compression.
There is no compression.Check the ignition.
Have a Yamaha dealer
check the vehicle.
Remove the spark plug
and check the electrodes.
3. IgnitionWe t
DryWipe off with a dry cloth and correct the
spark plug gap, or replace the spark plug.

3. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
4. 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.) WARNING! To prevent
damage or injury from spar-
king, make sure to ground
the spark plug electrodes
while turning the engine
over.
[EWA10951]
e. Remove the spark plug cap
from the spark plug, and theninstall the spark plug and the
spark plug cap.
5. Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
6. 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.
7. Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.
8. 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 6-24.
TIP
Make any necessary repairs before
storing the scooter.
