Oil level warning light “ ”
This warning light comes on when the
engine oil level is low.
The electrical circuit of the warning light
can be checked according to the fol-
lowing procedure.
1. Set the engine stop switch to “ ”
and turn the key to “ON”.
2. Shift the transmission into the neu-
tral position or pull the clutch lever.
3. Push the start switch. If the warn-
ing light does not come on while
pushing the start switch, have a
Yamaha dealer check the electri-
cal circuit.NOTE:_ Even if the oil level is sufficient, the
warning light may flicker when riding on
a slope or during sudden acceleration
or deceleration, but this is not a mal-
function. _

Fuel level warning light “ ”
This warning light comes on when the
fuel level drops below approximately
4.5 L. When this occurs, refuel as soon
as possible.
The electrical circuit of the warning light
can be checked according to the fol-
lowing procedure.
1. Set the engine stop switch to “ ”
and turn the key to “ON”.
2. Shift the transmission into the neu-
tral position or pull the clutch lever. 3. Push the start switch. If the warn-
ing light does not come on, have a
Yamaha dealer check the electri-
cal circuit.
NOTE:_ This model is equipped with a self-di-
agnosis device for the fuel level warn-
ing light circuit. (See page 3-4 for an
explanation of the self-diagnosis de-
vice.) _

Turn signal indicator light “ ”
This indicator light flashes when the
turn signal switch is pushed to the left
or right.

on.
EAU00095
Speedometer unit The speedometer unit is equipped with
a speedometer, an odometer and a
tripmeter. The speedometer shows
riding speed. The odometer shows the
total 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.

CAUTION:_ l
Immediately wipe off spilled fuel
with a clean, dry, soft cloth,
since fuel may deteriorate paint-
ed surfaces or plastic parts.
l
For Germany only: Whenever
replacement is necessary, use a
fuel tank cap of the same spe-
cial design as the original.
_
EAU00191
NOTE:_ If knocking (or pinging) occurs, use
gasoline of a different brand or with a
higher octane grade. _

Fuel tank breather hose Before operating the motorcycle:l
Check the fuel tank breather hose
connection.
l
Check the fuel tank breather hose
for cracks or damage, and replace
it if damaged.
l
Make sure that the end of the fuel
tank breather hose is not blocked,
and clean it if necessary.

WARNING
_ This shock absorber contains high-
ly pressurized nitrogen gas. For
proper handling, read and under-
stand the following information be-
fore handling the shock absorber.
The manufacturer cannot be held re-
sponsible for property damage or
personal injury that may result from
improper handling.l
Do not tamper with or attempt to
open the gas cylinder.
l
Do not subject the shock ab-
sorber to an open flame or other
high heat sources, otherwise it
may explode due to excessive
gas pressure.
l
Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.
l
Always have a Yamaha dealer
service the shock absorber.

EAU00324
Luggage strap holders There are four luggage strap holders
below the passenger seat, two of which
can be turned out for easier access.
EAU01571
EXUP system This motorcycle is equipped with
Yamaha’s EXUP (EXhaust Ultimate
Power valve) system. This system
boosts engine power by means of a
valve that regulates the diameter of the
exhaust pipe. The EXUP system valve
is constantly adjusted in accordance
with the engine speed by a computer-
controlled servomotor.
EC000027
CAUTION:_ l
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.
l
If the EXUP system does not op-
erate, have a Yamaha dealer
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
motorcycle upright.NOTE:_ The built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See further down for an explanation of
the ignition circuit cut-off system.) _
EW000044
WARNING
_ The motorcycle must not be ridden
with the sidestand down, or if the
sidestand cannot be properly
moved up (or does not stay up), oth-
erwise the sidestand could contact
the ground and distract the opera-
tor, resulting in a possible loss of
control. Yamaha’s ignition circuit
cut-off system has been designed to
assist the operator in fulfilling the
responsibility of raising the side-
stand before starting off. Therefore,
check this system regularly as de-
scribed below and have a Yamaha
dealer repair it if it does not function
properly. _
EAU03720
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.l
It prevents starting when the trans-
mission is in gear and the side-
stand is up, but the clutch lever is
not pulled.
l
It prevents starting when the trans-
mission is in gear and the clutch
lever is pulled, but the sidestand is
still down.
l
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.
EW000045
WARNING
_ If a malfunction is noted, have a
Yamaha dealer check the system
before riding. _

4-PRE-OPERATION CHECKSThe condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, to check the following points before each ride.
EAU03439

5-OPERATION AND IMPORTANT RIDING POINTS
EAU00373
WARNING
_ l
Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.
l
Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
l
Before starting out, make sure
that the sidestand is up. If the
sidestand is not raised com-
pletely, it could contact the
ground and distract the opera-
tor, resulting in a possible loss
of control.
_
EAU03818*

position.
l
The transmission is in gear with
the clutch lever pulled and the
sidestand up.
EW000054
WARNING
_ l
Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure

CAUTION:_ If the fuel level warning light comes
on, check the fuel level, and, if nec-
essary, refuel as soon as possible. _2. Shift the transmission into the neu-
tral position.NOTE:_ When the transmission is in the neutral
position, the neutral indicator light
should be on, otherwise have a
Yamaha dealer check the electrical cir-
cuit. _3. Turn the starter (choke) on and
