NOTE:The fuel tank cap cannot be closed un-
less the key is in the lock. In addition,
the key cannot be removed if the cap isnot properly closed and locked.
WARNING
EWA11090
Make sure that the fuel tank cap isproperly closed before riding.
EAU13220
Fuel Make sure that there is sufficient fuel in
the tank. When refueling, be sure to in-
sert the pump nozzle into the fuel tank
filler hole and to fill the tank to the bot-
tom of the filler tube as shown.
WARNING
EWA10880


Do not overfill the fuel tank, oth-
erwise it may overflow when the
fuel warms up and expands.


Avoid spilling fuel on the hot en-gine.
CAUTION:
ECA10070
Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since
fuel may deteriorate painted surfac-es or plastic parts.
EAU13390
CAUTION:
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-

3curs, use a gasoline of a different
brand. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.
EAU39450
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.
EAU13441
Catalytic converter This vehicle is equipped with catalytic
converters in the exhaust system.
WARNING
EWA10860
The exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before do-ing any maintenance work.CAUTION:
ECA10700
The following precautions must be
observed to prevent a fire hazard or
other damages.

Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.


Never park the vehicle near pos-
sible fire hazards such as grass
or other materials that easily
burn.


Do not allow the engine to idletoo long.

Helmet holding cable A helmet holding cable is provided in
the owner’s tool kit to secure two hel-
mets to the helmet cable holder
equipped on the bottom of the passen-
ger seat.
To secure a helmet with the helmet
holding cable
1. Remove the passenger seat. (See
page 3-19.)
2. Clip the middle snap hook of the
cable onto the cable holder.3. Pass one of the other snap hooks
of the cable through the helmet

Never ride with a helmet attached to
a helmet holding cable, since the
helmet may hit objects, causing lossof control and possibly an accident.
To release a helmet from the helmet
holding cable
1. Remove the passenger seat.
2. Unfasten the snap hooks from the
cable holder, and then remove the
cable from the helmet strap buck-
le.

Adjusting the front fork This front fork is equipped with spring
preload adjusting bolts, rebound damp-
ing force adjusting screws and com-
pression damping force adjusting bolts.
WARNING
EWA10180
Always adjust both fork legs equal-
ly, otherwise poor handling and lossof stability may result.
Spring preload
To increase the spring preload and
thereby harden the suspension, turn
the adjusting bolt on each fork leg in di-
rection (a). To decrease the spring pre-load and thereby soften the
suspension, turn the adjusting bolt on
each fork leg in direction (b).
NOTE:Align the appropriate groove on the ad-
justing mechanism with the top of thefront fork collar.Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting screw on each
fork leg in direction (a). To decrease the
rebound damping force and thereby
soften the rebound damping, turn the
adjusting screw on each fork leg in di-
rection (b).

NOTE:The compression damping force set-
ting is determined by measuring dis-
tance A, shown in the illustration. The
longer distance A is, the higher the
compression damping force; the short-
er distance A is, the lower the compres-sion damping force.To adjust the compression damping

may not exactly match the above spec-

production, the actual number of clicks
always represents the entire adjusting

it would be advisable to check the num-
ber of clicks of each damping force ad-

WARNING
EWA10220
This shock absorber contains highly
pressurized nitrogen gas. For prop-
er handling, read and understand
the following information before
handling the shock absorber. The
manufacturer cannot be held re-
sponsible for property damage or
personal injury that may result from
improper handling.

Do not tamper with or attempt to
open the gas cylinder.


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.

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.
EAU15301
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 described
