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. 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.
EAU13392
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 premium unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different
brand. Use of unleaded fuel will extend

Recommended fuel:
Premium unleaded gasoline only
Fuel tank capacity:
7.2 L (1.90 US gal, 1.58 Imp.gal)
Fuel reserve amount (when the fuel
level warning light comes on): 3.0 L (0.79 US gal, 0.66 Imp.gal)

OPERATION AND IMPORT ANT RIDING POINTS
EAU15952
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.
WARNING
EWA10272
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accidentor injury.
EAU56890
TIPThis model is equipped with:
a lean angle sensor to stop the en-
gine in case of a turnover. In this
case, the multi-function display in-
dicates error code 30, but this is
not a malfunction. Push the main
switch to “OFF” and then to “ON”
to clear the error code. Failing to
do so will prevent the engine from
starting even though the engine
will crank when pushing the start
switch.

an engine auto-stop system. The
engine stops automatically if left
idling for 20 minutes. In this case,
the multi-function display indicates
error code 70, but this is not a mal-
function. Push the start switch to
clear the error code and to restartthe engine.
EAU52906
Starting a cold engineNOTICE
ECA11043
For maximum engine life, never ac-
celerate hard when the engine iscold!
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 sid-
estand up.
See page 3-19 for more informa-
tion.
1. Push the main switch to “ON” and make sure that the engine stop
switch is set to “ ”.
The following warning lights
should come on for a few seconds,
then go off.


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 dis-
tances. 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 damag-
ing the engine, transmission,
and drive train, which are not
designed to withstand theshock of forced shifting.
EAU16811
Tips for reducing fuel
consumptionFuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
Shift up swiftly, and avoid high en-
gine speeds during acceleration.

Do not rev the engine while shifting
down, and avoid high engine
speeds with no load on the engine.

Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
EAU52941
Engine break-in
WARNING
EWA10322
Failure to properly maintain the ve-
hicle or performing maintenance ac-
tivities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha dealer performservice. 1. Before starting the engine, fill the fuel tank with the fuel.
2. Start and warm up the engine. Check the operation of the controls
and the engine stop switch. (See
page 3-7.) Then, restart the engine
and check its operation within no
more than 5 minutes after it is re-
started.
3. Operate the motorcycle in the low- er gears at moderate throttle open-
ings for five to eight minutes. Stop
the engine.
4. Check how the engine runs when the motorcycle is ridden with the
throttle 1/4 to 1/2 open (low to me-

ers and the brake caliper bracket
by inserting the wheel axle from
the left-hand side.TIP
Make sure that the retainer on the
brake caliper bracket is inserted
into the slot in the swingarm.

Make sure that there is enough
space between the brake pads be-fore installing the wheel.
3. Install the drive chain onto the rear sprocket. 4. Install the washer and the axle nut.
5. Lower the rear wheel so that it is
on the ground, and then put the
sidestand down.
6. Adjust the drive chain slack. (See page 6-25.)
7. Tighten the axle nut, and then the locknuts to their specified torques.
EAU25872
TroubleshootingAlthough Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur dur-
ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your motorcycle
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the motorcycle
properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look like
Yamaha parts, but they are often inferi-
or, have a shorter service life and can
lead to expensive repair bills.
WARNING
EWA15142
When checking the fuel system, do
not smoke, and make sure there are
no open flames or sparks in the ar-
ea, including pilot lights from water
