Fuel Make sure that there is sufficient fuel in
the tank. Fill the fuel tank to the bottom
of the filler tube as shown.
EW000130
WARNING
_

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


Avoid spilling fuel on the hot
engine.
_
EAU00186
CAUTION:_

Immediately wipe off spilled fuel
with a clean, dry, soft cloth,
since fuel may deteriorate paint-
ed surfaces or plastic parts.


For Germany only: Whenever
replacement is necessary, use a
fuel tank cap of the same spe-
cial design as the original.

EAU04255ECA00104
CAUTION:_ Use only unleaded gasoline. The
use of leaded gasoline will cause se-
vere damage to internal engine
parts, such as the valves and piston
rings, as well as to the exhaust sys-
tem. _Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use
of unleaded fuel will extend spark plug
life and reduce maintenance costs.

Storage compartment This storage compartment is designed
to hold an optional genuine Yamaha U-
LOCK. (Other locks may not fit.) When
placing a U-LOCK in the storage com-
partment, securely fasten it with the
straps. When the U-LOCK is not in the
storage compartment, be sure to se-
cure the straps to prevent losing them.
When storing the owner’s manual or
other documents in the storage com-
partment, be sure to wrap them in a
plastic bag so that they will not get wet.
When washing the motorcycle, be
careful not to let any water enter the
storage compartment.

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
screws.
EW000035
WARNING
_ Always adjust both fork legs equal-
ly, otherwise poor handling and loss
of 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 the

NOTE:_ Although the total number of clicks of
the rebound damping force adjusting
mechanism may not exactly match the
above specifications due to small dif-
ferences in production, the actual num-
ber of clicks always represents the
entire adjusting range. To obtain a pre-
cise adjustment, it would be advisable
to check the number of clicks of the re-
bound damping force adjusting mecha-
nism and to modify the specifications
as necessary. _
Compression damping force
To harden the compression damping,
decrease the setting by turning the ad-
justing screw. To soften the compres-
sion damping, increase the setting by
turning the adjusting screw. Make sure
that the position indicator is aligned
with the appropriate setting.CI-10EEAU00315
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.

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 dealer
service the shock absorber.

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. _

EAU00373
WARNING
_

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 loss
of control.

EAU03818*
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
sidestand up.
EW000054
WARNING
_

Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-20.


Never ride with the sidestand
down.
_1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “”.
EC000035
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
completely close the throttle. (See
page 3-11 for starter (choke) oper-
ation.)
