sure to distribute the weight as
evenly as possible on both sides
of the scooter to minimize imba-
lance or instability.
Shifting weights can create a
sudden imbalance. Make sure
that accessories and cargo are
securely attached to the scooter
before riding. Check accessory
mounts and cargo restraints fre-
quently.
Never attach any large or heavy
items to the handlebar, front fork,
or front fender. Such items can
create unstable handling or a
slow steering response.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this scooter. Since Yamaha cannot
test all other accessories that may be
available, you must personally be res-
ponsible for the proper selection, ins-
tallation and use of non-Yamaha
accessories. Use extreme caution
when selecting and installing any
accessories.Keep the following guidelines in mind,
as well as those provided under “Loa-
ding” when mounting accessories.
Never install accessories or carry
cargo that would impair the per-
formance of your scooter. Care-
fully inspect the accessory befo-
re using it to make sure that it
does not in any way reduce
ground clearance or cornering
clearance, limit suspension tra-
vel, steering travel or control ope-
ration, or obscure lights or reflec-
tors.
• Accessories fitted to the hand-
lebar or the front fork area can
create instability due to impro-
per weight distribution or
aerodynamic changes. If
accessories are added to the
handlebar or front fork area,
they must be as lightweight as
possible and should be kept to
a minimum.
• Bulky or large accessories may
seriously affect the stability of
the scooter due to aerodyna-
mic effects. Wind may attempt
to lift the scooter, or the scoo-ter may become unstable in
cross winds. These accesso-
ries may also cause instability
when passing or being passed
by large vehicles.
• Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the fre-
edom of movement of the ope-
rator and may limit control abi-
lity, therefore, such
accessories are not recom-
mended.
Use caution when adding electri-
cal accessories. If electrical
accessories exceed the capacity
of the scooter’s electrical system
an electric failure could result,
which could cause a dangerous
loss of lights or engine power.
Gasoline and exhaust gas
GASOLINE IS HIGHLY FLAMMA-
BLE:
• Always turn the engine off
when refueling.
• Take care not to spill any gaso-
line on the engine or exhaust
system when refueling.

Fuel
1. Fuel tank filler tube
2. Fuel level
Make sure that there is sufficient fuel
in the tank. When refueling, be sure to
insert the pump nozzle into the fuel
tank filler hole and to fill the tank to
the bottom of the filler tube as shown.

WARNING
Do not overfill the fuel tank,
otherwise it may overflow
when the fuel warms up and
expands.
Avoid spilling fuel on the hot
engine.
ECA10070
CAUTION:
Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since
fuel may deteriorate painted surfa-
ces or plastic parts.
EAU33520
ECA11400
CAUTION:
Use only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and piston
rings, as well as to the exhaust sys-
tem.
Your Yamaha engine has been desig-
ned to use regular unleaded gasoline
with a research octane number of 91
or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use
of unleaded fuel will extend spark
plug life and reduce maintenance
costs.
Recommended fuel:

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.)
e. Remove the spark plug cap from
the spark plug, and then install
the spark plug and the spark plug
cap.EWA10950

WARNING
To prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turning
the engine over.
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 moreinformation on storing the bat-
tery, see page 6-24.
NOTE:
Make any necessary repairs before
storing the scooter.
