Open the lid, insert the key into the lock,
and then turn it 1/4 turn clockwise. The
lock will be released and the fuel tank
cap can be removed.
To install the fuel tank cap
1. Inser t the fuel tank cap into the tank
opening with the key inserted in the
lock and the match marks aligned.2. Turn the key counterclockwise to
the original position, remove it, and
then close the lid.
TIP
The fuel tank cap cannot be installed
unless the key is in the lock. In addi-
tion, the key cannot be removed if the
cap is not properly installed and locked.

WARNING
Make sure that the fuel tank cap is
properly installed before riding. Leak-
ing fuel is a fire hazard.

smoking, or while in the vicinity of
sparks, open flames, or other
sources of ignition such as the pi-
lot lights of water heaters and
clothes dryers.
2. Do not overfill the fuel tank. Stop
filling 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 immedi-
ately.
NOTICE:
Immediately wipe
off spilled fuel with a clean, dry,
soft cloth, since fuel may dete-
riorate painted surfaces or plas-
tic parts.
[ECA10071]
4. Be sure to securely close the fuel
tank cap.

WARNING
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gasoline
by mouth. If you should swallowsome gasoline or inhale a lot of gaso-
line vapor, or get some gasoline in
your eyes, see your doctor immedi-
ately. If gasoline spills on your skin,
wash with soap and water. If gaso-
line spills on your clothing, change
your clothes.

Recommended fuel:
REGULAR UNLEADED GASOLINE
ONLY
Fuel tank capacity:
4.5 L (1.19 US gal) (0.99 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 piston rings, as well
as to the exhaust system.Your Yamaha engine has been designed
to use regular unleaded gasoline with a
research octane number of 91 or higher.
If knocking (or pinging) occurs, use a

WARNING
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.1. Before refueling, turn off the engine
and be sure that no one is sitting
on the vehicle. Never refuel while Fuel

stabilizer (if available) to prevent the
fuel tank from rusting and the fuel
from deteriorating.
3. Perform the following steps to pro-
tect 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 dam-
age or injury from sparking,
make sure to ground the sparkplug 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. Alterna-
tively, 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 plas-
tic bag to prevent moisture from en-
tering 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 6-19. Storage
EAU36561
StorageShort-term
Always store your scooter in a cool, dry
place and, if necessary, protect it against
dust with a porous cover.
ECA10820
NOTICE● ●● ●
●
Storing the scooter in a poorly
ventilated room or covering it
with a tarp, while it is still wet,
will allow water and humidity to
seep in and cause rust.
● ●● ●
●
To prevent corrosion, avoid
damp cellars, stables (because of
the presence of ammonia) and
areas where strong chemicals are
stored.
Long-term
Before storing your scooter for several
months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Fill up the fuel tank and add fuel
