1. Fuel tank cap lock cover
2. Unlock
To open the fuel tank cap
Open the fuel tank cap lock cover,
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 opened.
1. Lock
To close the fuel tank cap1. Push the fuel tank cap into posi- tion with the key inserted in the
lock.
2. Turn the key counterclockwise to the original position, remove it,
and then close the lock cover.
TIP
The fuel tank cap cannot be closed
unless the key is in the lock. In addi-
tion, the key cannot be removed if the
cap is not properly closed and loc-
ked.
EWA11091
Make sure that the fuel tank cap is
properly closed after filling fuel.
Leaking fuel is a fire hazard.

Fuel
Make sure there is sufficient gasoline
in the tank.
EWA10881
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 engi-ne and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the
vicinity of sparks, open flames, or
other sources of ignition such as
the pilot 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.
1. Fuel tank filler tube
2. Maximum fuel level
3. Wipe up any spilled fuel imme-diately. NOTICE: Immediately
wipe off spilled fuel with a cle-
an, dry, soft cloth, since fuel
may deteriorate painted surfa-
ces or plastic parts.
[ECA10071]
4. Be sure to securely close the fuel tank cap.
EWA15151
Gasoline is poisonous and can cau-
se injury or death. Handle gasoline
with care. Never siphon gasoline by
mouth. If you should swallow some
gasoline or inhale a lot of gasoline vapor, or get some gasoline in your
eyes, see your doctor immediately.
If gasoline spills on your skin, wash
with soap and water. If gasoline
spills on your clothing, change your
clothes.
EAU13270
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:
REGULAR UNLEADED
GASOLINE ONLY
Fuel tank capacity: 13.8 L (3.65 US gal, 3.04 Imp.gal)
Fuel reserve amount: 2.2 L (0.58 US gal, 0.48 Imp.gal)

Checking the spark plug
The spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause
any spark plug to slowly erode, the
spark plug should be removed and
checked in accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
To remove the spark plug1. Remove panel A. (See page 6-8).
2. Remove the spark plug cap.

2. Turn the fuel cock lever to “OFF”.
3. Drain the carburetor float cham-ber by loosening the drain bolt;
this will prevent fuel deposits
from building up. Pour the drai-
ned fuel into the fuel tank.
4. Fill up the fuel tank and add fuel stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
5. 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]
6. Lubricate all control cables andthe pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
7. Check and, if necessary, correct the tire air pressure, and then lift
the motorcycle 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.
8. Cover the muffler outlet with a plastic bag to prevent moisture
from entering it.
9. 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 6-32.
TIP
Make any necessary repairs before
storing the motorcycle.
