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.


Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.


Always have a Yamaha dealerservice the shock absorber.

Luggage strap holders There is a luggage strap holder on each
passenger footrest.

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 diameter of the exhaust pipe.
The EXUP system valve is constantly
adjusted in accordance with the engine
speed by a computer-controlled servo-
motor.CAUTION:
ECA15610
The EXUP system has been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-mance of or damage to the engine.

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.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 ofthe ignition circuit cut-off system.)
WARNING
EWA10240
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 as describedbelow and have a Yamaha dealer re-
pair it if it does not function proper-
ly.
EAU15321
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 sid-
estand is moved down.
Periodically check the operation of the
ignition circuit cut-off system according
to the following procedure.WARNING
EWA10260


The vehicle must be placed on
the centerstand during this in-
spection.


If a malfunction is noted, have a
Yamaha dealer check the sys-tem before riding.

WARNING
EWA10270


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.


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.


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 lossof control.
EAU44720
Starting the engine 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.WARNING
EWA10290


Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-25.


Never ride with the sidestanddown.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to“”.

sponding warning and indicator
light circuit check.
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. Start the engine by pushing the

attempt.CAUTION:
ECA16040


If the oil level warning light flick-
ers or remains on after starting,
immediately stop the engine,
and then check the engine oil
level and the vehicle for oil leak-
age. If necessary, add engine
oil, and then check the warning
light again.


If the coolant temperature warn-
ing light flickers or remains on
after starting, immediately stop
the engine, and then check the
coolant level and the vehicle for
coolant leakage. If necessary,
add coolant, and then check the
warning light again.


If the engine trouble warning
light flashes or remains on after
starting, immediately stop the
engine, and have a Yamaha
dealer check the cause.


For ABS model only
If the ABS warning light flashes
or remains on after starting, the
ABS may be defective, and the
brake system reverts to conven-
tional braking.
If this occurs, have a Yamaha
dealer check the system as
soon as possible.


The immobilizer system indica-
tor light should come on when
the key is turned to “ON”, and
then go off after a few seconds.
If the indicator light does not
come on, or does not go off, or
if it flashes and the display indi-
cates a two-digit error code,
have a Yamaha dealer check theelectrical circuit.

CAUTION:
ECA10260


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.
EAU16810
Tips for reducing fuel con-
sumption Fuel 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).
EAU16841
Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU17091
0–1000 km (0–600 mi)
Avoid prolonged operation above 6000
r/min.
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 7200
r/min.
