seconds, then go off, have a Yamaha
dealer check the electrical circuit.
EAU11444
Coolant temperature warning
light “u”
This warning light comes on if the en-
gine overheats. If this occurs, stop the
engine immediately and allow the en-
gine to cool. The electrical circuit of the
warning light can be checked by turn-
ing the key to "ON". The warning light
should come on for a few seconds,and then go off. If the warning light
does not come on initially when the
key is turned to "ON", or if the warning
light remains on, have a Yamaha deal-
er check the electrical circuit.
ECA10021
NOTICE
Do not continue to operate the en-
gine if it is overheating.
TIP
●For radiator-fan-equipped vehi-
cles, the radiator fan(s) automati-
cally switch on or off according to
the coolant temperature in the ra-
diator.
●If the engine overheats, see page
7-41 for further instructions.
EAU11534
Engine trouble warning light “U”
This warning light comes on or flashes
if a problem is detected in the electri-
cal circuit monitoring the engine. If this
occurs, have a Yamaha dealer check
the self-diagnosis system. (See page
4-8 for an explanation of the self-diag-
nosis device.) The electrical circuit of
the warning light can be checked byturning the key to "ON". The warning
light should come on for a few seconds,
and then go off. If the warning light does
not come on initially when the key is
turned to "ON", or if the warning light re-
mains on, have a Yamaha dealer check
the electrical circuit.
EAU26876
Immobilizer system indicator
light “ ”
The electrical circuit of the indicator
light can be checked by turning the
key to "ON". The indicator light should
come on for a few seconds, and then
go off. If the indicator light does not
come on initially when the key is
turned to "ON", or if the indicator light
remains on, have a Yamaha dealer
check the electrical circuit.
When the key is turned to "OFF" and
30 seconds have passed, the indicator
light will start flashing indicating the
immobilizer system is enabled. After
24 hours have passed, the indicator
light will stop flashing, however the im-
mobilizer system is still enabled.
This model is also equipped with a
self-diagnosis device for the immobi-
lizer system. (See page 4-8 for an ex-
planation of the self-diagnosis device.)

Self-diagnosis devices
1. Engine trouble warning light “U”
2. Immobilizer system indicator light “ ”
This model is equipped with a self-di-
agnosis device for various electrical
circuits.
If any of those circuits are defective,
the engine trouble warning light will
start flashing. If this occurs, have a
Yamaha dealer check the vehicle.
This model is also equipped with a
self-diagnosis device for the immobi-
lizer system.
If any of the immobilizer system cir-
cuits are defective, the immobilizer
system indicator light will start flash-
ing.
If this occurs, have a Yamaha dealer
check the vehicle.
TIP
If the indicator light slowly flashes five
times, and then quickly flashes two
times repeatedly, this error could be
caused by transponder interference. If
this occurs, try the following.
1. Use the code re-registering key to
start the engine.
TIP
Make sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobiliz-
er key on the same key ring! Immobi-
lizer system keys may cause signal in-
terference, which may prevent the
engine from starting.2. If the engine starts, turn it off, and
try starting the engine with the
standard keys.
3. If one or both of the standard keys
do not start the engine, take the
vehicle, the code re-registering
key and both standard keys to a
Yamaha dealer and have the
standard keys re-registered.
If the immobilizer system indicator
light continues to flash, have a Yama-
ha dealer check the vehicle.

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.

WARNING0
The vehicle must not be ridden
with the sidestand down, or if the
sidestand cannot be properly
moved up (or does not stay up),
otherwise the sidestand could con-
tact the ground and distract the
operator, resulting in a possible
loss of control. Yamaha’s ignition
circuit cut-off system has been de-
signed to assist the operator in ful-
filling the responsibility of raising
the sidestand before starting off.
Therefore, check this system regu-
larly as described below and have
a Yamaha dealer repair it if it does
not function properly.
EAU15301
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 motorcycle upright.
TIP
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situa-
tions. (See further down for an expla-
nation of the ignition circuit cut-off sys-
tem.)

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 side-
stand 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 accord-
ing to the following procedure.
TIP
This check is most reliable if per-
formed with a warmed-up engine.
