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.
EAU13320
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 regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different brandor premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.

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.
EAU13442
Catalytic converters 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.

Storage compartment (FZ1-N)This storage compartment is designed
to hold an optional genuine Yamaha
CYCLELOK. (Other locks may not fit.)
When placing a CYCLELOK in the stor-
age compartment, securely fasten it
with the straps. When the CYCLELOK
is not in the storage compartment, be
sure to secure the straps to prevent los-
ing 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 Each front fork leg is equipped with a
spring preload adjusting bolt, the right
front fork leg is equipped with a re-
bound damping force adjusting screw
and the left front fork leg with a com-
pression damping force adjusting
screw.
WARNING
EWA14670
Always adjust the spring preload on
both fork legs equally, otherwise
poor handling and loss of stabilitymay result.

each fork leg in direction (b).
NOTE:Align the appropriate groove on the ad-
justing mechanism with the top of thefront fork cap bolt.Rebound damping force
The rebound damping force is adjusted
on the right front fork leg only. To in-
crease the rebound damping force and

Never attempt to turn an adjusting
mechanism beyond the maximum orminimum settings.
NOTE:Although the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above spec-
ifications due to small differences in

it would be advisable to check the num-
ber of clicks of each damping force ad-
justing mechanism and to modify thespecifications as necessary.

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

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 describedbelow and have a Yamaha dealer re-
pair it if it does not function proper-
ly.

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
