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)

Fuel tank breather/overflow
hose
1. Fuel tank breather hose and overflow hose
Before operating the motorcycle:
Check the fuel tank breather/
overflow hose connection.
Check the fuel tank
breather/overflow hose for
cracks or damage, and replace it
if damaged.
Make sure that the end of the fuel
tank breather/overflow hose is
not blocked, and clean it if
necessary.
Make sure that the end of the fuel
tank breather/overflow hose is
positioned inside of the clamp.
EAU13433
Catalytic converter
This model is equipped with a cataly-
tic converter in the exhaust system.
EWA10862
The exhaust system is hot after
operation. To prevent a fire 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 befo-
re 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.
ECA10701
Use only unleaded gasoline. The
use of leaded gasoline will cause
unrepairable damage to the cataly-
tic converter.

Fuel cock
The fuel cock supplies fuel from the
tank to the carburetor while filtering it
also.
The fuel cock has three positions:
OFF
1. Pointed end positioned over “OFF”
With the lever in this position, fuel will
not flow. Always return the lever to
this position when the engine is not
running.ON
1. Pointed end positioned over “ON”
With the lever in this position, fuel
flows to the carburetor. Normal riding
is done with the lever in this position.
RES
1. Pointed end positioned over “RES”
This indicates reserve. If you run out
of fuel while riding, move the lever to
this position. Fill the tank at the first
opportunity. Be sure to set the lever
back to “ON” after refueling!

Sidestand
1. Sidestand
The sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the vehicle upright.
TIP
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain
situations. (See the following section
for an explanation of the ignition cir-
cuit cut-off system.)
EWA10241
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control. Yama-
ha’s ignition circuit cut-off system
has been designed to assist the
operator in fulfilling the responsibi-
lity of raising the sidestand before
starting off. Therefore, check this
system regularly and have a Yama-
ha dealer repair it if it does not
function properly.
EAU15314
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch,
clutch switch and neutral switch) has
the following functions.
It prevents starting when the
transmission is in gear and the
sidestand is up, but the clutch
lever is not pulled.
It prevents starting when the
transmission is in gear and the
clutch lever is pulled, but the
sidestand is still down.
It cuts the running engine when
the transmission is in gear and
the sidestand is moved down.
Periodically check the operation of
the ignition circuit cut-off system
according to the following procedure.
TIP
This check is most reliable if perfor-
med with a warmed-up engine.

EAU15951
Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do
not understand, ask your Yamaha
dealer.
EWA10271
Failure to familiarize yourself with
the controls can lead to loss of
control, which could cause an acci-
dent or injury.
EAU16055
Starting a cold engine
In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
The transmission is in the neutral
position.
The transmission is in gear with
the clutch lever pulled and the
sidestand up.
See page 3-14 for more information. 1. Turn the fuel cock lever to “ON”.
2. Turn the key to “ ” and make sure that the engine stop switch
is set to “ ”.
3. Shift the transmission into the neutral position. The neutral indi-
cator light should come on. If not,
ask a Yamaha dealer to check the
electrical circuit.
4. Turn the starter (choke) on and completely close the throttle.
(See page 3-12).
5. Start the engine by pushing the start switch.
If the engine fails to start, release
the start switch, wait a few
seconds, and then try again.
Each starting attempt should be as short as possible to preserve
the battery. Do not crank the
engine more than 10 seconds on
any one attempt.
6. After starting the engine, move the starter (choke) back halfway.
7. When the engine is warm, turn the starter (choke) off.
TIP
The engine is warm when it responds
quickly to the throttle with the starter
(choke) turned off.
ECA11042
For maximum engine life, never
accelerate hard when the engine is
cold!
