To close the fuel tank cap
1. 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 locked.
EWA11091
WARNING0
Make sure that the fuel tank cap is
properly closed after filling fuel.
Leaking fuel is a fire hazard.
EAU13221
Fuel
Make sure there is sufficient gasoline
in the tank.
EWA10881
WARNING0
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 en-
gine and be sure that no one is
sitting 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. When
refueling, be sure to insert the
pump nozzle into the fuel tank
filler hole. Stop filling when the fu-
el 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. Fuel level
3. Wipe up any spilled fuel immedi-
ately. NOTICE:Immediately wipe
off spilled fuel with a clean, dry,
soft cloth, since fuel may deteri-
orate painted surfaces or plas-
tic parts.
4. Be sure to securely close the fuel
tank cap.
EWA15151
WARNING0
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swal-
low some gasoline or inhale a lot of
gasoline vapor, or get some gaso-
line in your eyes, see your doctor
immediately. If gasoline spills on

Fuel tank breather hose
1. Fuel tank breather hose
2. Clamp
Before operating the motorcycle:
●Check the fuel tank breather hose
connection.
●Check the fuel tank breather hose
for cracks or damage, and replace
it if damaged.
●Make sure that the fuel tank
breather hose is not blocked, and
clean it if necessary.
ECA11400
NOTICE
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 system.
Your Yamaha engine has been de-
signed to use premium unleaded
gasoline with a research octane num-
ber of 95 or higher. If knocking (or
pinging) occurs, use a gasoline of a
different brand. Use of unleaded fuel
will extend spark plug life and reduce
maintenance costs.
Recommended fuel:
PREMIUM UNLEADED
GASOLINE ONLY
Fuel tank capacity:
23.0 L (6.07 US gal) (5.05 Imp.gal)
Fuel reserve amount (when the fuel
level warning light comes on):
6.7 L (1.77 US gal) (1.47 Imp.gal)
EAU13433
Catalytic converter
This model is equipped with a catalyt-
ic converter in the exhaust system.
EWA10862
WARNING0
The exhaust system is hot after op-
eration. 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 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.

OPERATION AND IMPORTANT RIDING POINTS
3. Start the engine by pushing the
start switch.
TIP
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 pre-
serve the battery. Do not crank the en-
gine more than 10 seconds on any one
attempt.
ECA11040
NOTICE
For maximum engine life, never ac-
celerate hard when the engine is
cold!
TIP
The engine is warm when it quickly re-
sponds to the throttle.

Shifting
1. Shift pedal
N. Neutral position
Shifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing
hills, etc.
The gear positions are shown in the il-
lustration.
TIP
To shift the transmission into the neu-
tral position, press the shift pedal down
repeatedly until it reaches the end of its
travel, and then slightly raise it.

If a warning or indicator light does
not go off, see page 4-3 for the cor-
responding warning and indicator
light circuit check.
2. Shift the transmission into the
neutral position.
TIP
When the transmission is in the neu-
tral position, the neutral indicator light
should be on, otherwise have a Yama-
ha dealer check the electrical circuit.

ECA10260CAUTION:
Even with the transmission in
the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long
distances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.
Always use the clutch while
changing gears to avoid dam-
aging the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.
EAU16810
Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
Shift up swiftly, and avoid high en-
gine speeds during acceleration.
Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the en-
gine.
Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
EAU16841
Engine break-in
There is never a more important peri-
od in the life of your engine than the
period between 0 and 1600 km (1000
mi). For this reason, you should read
the following material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts
in the engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheating
must be avoided.

2. Remove the spark plug as shown,
with the spark plug wrench includ-
ed in the owner’s tool kit.
To check the spark plug
1. Check that the porcelain insulator
around the center electrode of the
spark plug is a medium-to-light
tan (the ideal color when the vehi-
cle is ridden normally).
TIP
If the spark plug shows a distinctly dif-
ferent color, the engine could be oper-
ating improperly. Do not attempt to di-
agnose such problems yourself.
Instead, have a Yamaha dealer check
the vehicle.
2. Check the spark plug for elec-
trode erosion and excessive car-
bon or other deposits, and re-
place it if necessary.
Specified spark plug:
CR7E (NGK)
Spark plug gap:
0.7-0.8 mm (0.028-0.032 in)
To install the spark plug
1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specification.
1. Spark plug gap
2. Clean the surface of the spark
plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then tight-
en it to the specified torque.
EAU19603
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 peri-
odic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
To remove the spark plug
1. Spark plug cap
2. Spark plug wrench
1. Remove the spark plug cap.

Engine oil and oil filter
element
The engine oil level should be checked
before each ride. In addition, the oil must
be changed and the oil filter element re-
placed at the intervals specified in the
periodic maintenance and lubrication
chart.
To check the engine oil level
1. Place the vehicle on a level surface
and hold it in an upright position.
TIP
Make sure that the vehicle is posi-
tioned straight up when checking the
oil level. A slight tilt to the side can re-
sult in a false reading.
2. Start the engine, warm it up for
10-15 minutes and then turn it off.
3. Remove the oil filler cap, wipe the
dipstick clean, insert it back into
the oil filler hole (without screwing
it in), and then remove it again to
check the oil level.
1. Engine oil filler cap
2. Maximum level mark
3. Minimum level mark
TIP
●The engine oil tank is located in-
side of the frame.
●The engine oil should be between
the minimum and maximum level
marks.
Tightening torque:
Spark plug:
12.5 Nm (1.25 m·kgf, 9.0 ft·lbf)
TIP
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4-
1/2 turn past finger tight. However, the
spark plug should be tightened to the
specified torque as soon as possible.
4. Install the spark plug cap.
