Rear brake lever

1. Rear brake leverThe rear brake lever is located on the
left handlebar grip. To apply the rear
brake, pull the lever toward the han-
dlebar grip.
This model is equipped with a unifi ed
brake system.
When pulling the rear brake lever, the
rear brake and a portion of the front
brake are applied. For full braking
performance, apply both brake levers
simultaneously.TIP● As the unified brake system is
mechanical, additional free play
can be felt in the front brake lever
when the rear brake lever is be-
ing pulled.
● The unified brake system does
not function when the front brake
is applied alone.

in the tank.
EWA10881
WARNING
Gasoline and gasoline vapors are
extremely ammable. To avoid res
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.
1. Before refueling, turn off the en-
gine and be sure that no one is
sitting on the vehicle. Never re-
fuel while smoking, or while in the
vicinity of sparks, open fl ames, or
other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfi ll the fuel tank. When
refueling, be sure to insert the
pump nozzle into the fuel tank fi ll-
er hole. Stop fi lling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine
or the sun can cause fuel to spill
out of the fuel tank.
3. Wipe up any spilled fuel im-
mediately.
NOTICE:
Immedi-
ately wipe off spilled fuel with a
clean, dry, soft cloth, since fuel
may deteriorate painted sur-
faces or plastic parts.[ECA10071]
4. Be sure to securely close the fuel
tank cap.
EWA15151
WARNING
Gasoline is poisonous and can
cause injury or death. Handle
gasoline with care. Never siphon
gasoline by mouth. If you should
swallow some gasoline or inhale a

gasoline in your eyes, see your
doctor immediately. If gasoline
spills on your skin, wash with soap

clothing, change your clothes.
EAU33521
Recommended fuel:
REGULAR UNLEADED GASOLINE
ONLY
Fuel tank capacity:
8.0 L (2.11 US gal) (1.76 Imp.gal)
ECA11400
NOTICEUse only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and pis-
ton rings, as well as to the exhaust
system.
Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line 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.
EAU13433
Catalytic converterThis model is equipped with a cata-
lytic converter in the exhaust system.
EWA10862
WARNING
The exhaust system is hot after op-
eration. To prevent a re hazard or
burns:● Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.● Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.● Make sure that the exhaust
system has cooled down be-
fore doing any maintenance
work.● Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.

SCOOTER CARE AND STORAGE
the fuel tank from rusting and the
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 spark-
ing 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 elec-
trodes while turning the en-
gine 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 degraded
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
place [less than 0 °C (30 °F) or
more than 30 °C (90 °F)]. For
more information on storing the
battery, see page 6-26.
TIPMake any necessary repairs before
storing the scooter.
