This model is equipped with a self-diag-
nosis device for various electrical cir-
cuits.
If a problem is detected in any of those
circuits, the engine trouble warning light
will come on or flash, and the odome-
ter/tripmeter/clock display will indicate
an error code.
If the odometer/tripmeter/clock display
indicates any error codes, note the
code number, and then have a Yamaha
dealer check the vehicle.
The self-diagnosis
device also detects
problems in the immobilizer system cir-
cuits. If a problem is detected in the immobi-
lizer system circui
ts, the immobilizer
system indicator light will flash, and the
display will indicate an error code.
TIPIf the display indicates error code 52,
this could be caused by transponder in-
terference. If this error code appears,
try the following.1. Use the code re-registering key to start the engine.TIPMake sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobilizer
key on the same key ring! Immobilizer
system keys may cause signal interfer-
ence, which may prevent the engine
from starting.2. If the engine starts, turn it off andtry starting the engine with the
standard keys.

Fuel Make sure there is sufficient gasoline in
the tank.
WARNING
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 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.
[ECA10071]
4. Be sure to securely close the fuel tank cap.
WARNING
EWA15151
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.
EAU13391
NOTICE
ECA11400
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-

Fuel tank breather/overflow
hose Before operating the motorcycle:●
Check the fuel tank breather/over-
flow hose connection.
●
Check the fuel tank breather/over-
flow 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 po-
sitioned inside of the clamp.

Catalytic converter This model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10862
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 sys-
tem has cooled down before do-
ing any maintenance work.
●
Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.

[ECA10121]WARNING
EWA10221
This shock absorber assembly con-
tains highly pressurized nitrogen
gas. Read and understand the fol-
lowing information before handling
the shock absorber assembly.●
Do not tamper with or attempt to
open the cylinder assembly.
●
Do not subject the shock ab-
sorber assembly to an open
flame or other high heat source.
This may cause the unit to ex-
plode due to excessive gas
pressure.
●
Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.
●
Do not dispose of a damaged or
worn-out shock absorber as-
sembly yourself. Take the shock
absorber assembly to a Yamaha
dealer for any service.

EXUP system This model is equipped with Yamaha’s
EXUP (EXhaust Ultimate Power valve)
system. This system boosts engine
power by means of a valve that regu-
lates the inner diameter of the exhaust
pipe. The EXUP system valve is con-
stantly adjusted in accordance with the
engine speed by a computer-controlled
servomotor.NOTICE
ECA10191
●
The EXUP system has been set
and extensively tested at the
Yamaha factory. Changing these settings without sufficient
technical knowledge may result
in poor performance of or dam-
age to the engine.
●
If the EXUP system cannot be
heard when the main switch is
turned on, have a Yamaha deal-
er check it.

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.TIPThe 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 expla-
nation of the ignition circuit cut-off sys-
tem.)
WARNING
EWA10241
The vehicle must not be ridden with
the sidestand down, or if the side-
stand 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.
Yamaha’s ignition circuit cut-off system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check this system regularly and have a
Yamaha dealer repair it if it does not function properly.
EAU44892
Ignition circuit cut-off system The ignition circuit cut-off system (com-
prising the sidestand switch, clutch
switch and neutral switch) has the fol-
lowing functions.●
It prevents starting when the trans-
mission is in gear and the side-
stand is up, but the clutch lever is not pulled.
●
It prevents starting when the trans-
mission is in gear and the clutch le-
ver 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.
