l
When the coolant temperature is
too high, the warning light comes
on and symbol “ ” flashes. Stop
the motorcycle and allow it to idle
until the coolant temperature goes
down. If the temperature does not
go down, stop the engine. (See
the “Engine overheating” section
on page 6-46 for further instruc-
tions.)
l
When the engine oil level is low
and the coolant temperature is too
high, the warning light flashes and

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.

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.

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
ventilation.
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.
@
EAU01382*
Starting a cold engine In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:l
The transmission is in the neutral
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
described on page 3-24.
l
Never ride with the sidestand
down.
@1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “ ”.
ECA00005
CAUTION:@ The oil level/coolant temperature
warning light and fuel level warning
light should come on for a few sec-
onds, then go off. If a warning light
does not go off, see page 3-4 for the
corresponding warning 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
circuit. @3. Turn the starter (choke) on and
completely close the throttle. (See
page 3-13 for starter (choke)
operation.)
4. Start the engine by pushing the
start switch.

EAU00423
Shifting Shifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing hills,
etc.
The gear positions are shown in the
illustration.NOTE:@ To shift the transmission into the neu-
tral position, press the shift pedal down
repeatedly until it reaches the end of its
travel, and then slightly raise it. @
EC000048
CAUTION:@ l
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.
l
Always use the clutch while
changing gears to avoid dam-
aging the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.

Tips for reducing fuel
consumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:l
Thoroughly warm up the engine.
l
Turn the starter (choke) off as
soon as possible.
l
Shift up swiftly, and avoid high en-
gine speeds during acceleration.
l
Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the engine.
l
Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
