Speedometer unitThe speedometer unit is equipped with
a speedometer, an odometer and a
tripmeter. The speedometer shows rid-
ing speed. The odometer shows the to-
tal distance traveled. The tripmeter
shows the distance traveled since it
was last set to zero with the reset knob.
The tripmeter can be used to estimate
the distance that can be traveled with a
full tank of fuel. This information will en-
able you to plan future fuel stops.1. Reset knob

Fuel tank capTo remove the fuel tank cap
Slide the fuel tank cap lock cover open,
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. Insert the fuel tank cap into the tank opening with the key inserted
in the lock and with the “ ” mark
facing forward. 2. Turn the key counterclockwise to
the original position, remove it, and
then close the lock cover.
TIPThe fuel tank cap cannot be installed
unless the key is in the lock. In addition,
the key cannot be removed if the cap isnot properly installed and locked.
WARNING
EWA10132
Make sure that the fuel tank cap is
properly installed before riding.Leaking fuel is a fire hazard.
EAU13222
FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, followthese instructions.
1. Before refueling, turn off the en- gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity 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 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 deteri-
orate painted surfaces or plastic
parts.
[ECA10072]
4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swallow
some gasoline or inhale a lot of gas-
oline 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.
EAU57690
NOTICE
ECA11401
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 regular unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different brandor premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that contain-
ing methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.

Recommended fuel:
Regular unleaded gasoline (Gasohol
(E10) acceptable)
Fuel tank capacity: 12.0 L (3.17 US gal, 2.64 Imp.gal)
Fuel reserve amount (when the fuel
level warning light comes on):
2.2 L (0.58 US gal, 0.48 Imp.gal)

TIPThis model is equipped with:
a lean angle sensor to stop the en-
gine in case of a turnover. In this
case, turn the key to “OFF” and
then to “ON”. Failing to do so will
