TIPThis fuel meter is equipped with a self-
diagnosis system. If a problem is de-
tected in the electrical circuit, the fol-
lowing cycle is repeated until the
malfunction is corrected: fuel level seg-
ments flash eight times, then go off for
approximately three seconds. If this
occurs, have a Yamaha dealer check
the electrical circuit.Coolant temperature meter
The coolant temperature meter indi-
cates the temperature of the coolant.
When the key is turned to “ ”, the dis-
play segments of the digital coolant
temperature meter will sweep onceacross the temperature range and then
return to “C” in order to test the electri-
cal circuit.
If the last segment on the right flashes,
stop the vehicle, then stop the engine,
and let the engine cool. (See page
6-38.)
NOTICE

Do not continue to operate the en-
g

changes in the weather and engine
load.

3To switch between the average fuel
consumption displays, push the “SEL”
button for one second.
To reset the average fuel consumption
display, push the “RES” button for at
least one second.
TIPAfter resetting the average fuel con-
sumption display, “_ _._” is shown until
the vehicle has traveled 1 km (0.6 mi).Oil chan
ge tripmeter
The oil change tripmeter shows the
distance traveled since it was last reset
(i.e., since the last oil change). The oil change indicator “OIL” will flash
at the initial 1000 km (600 mi), then at
5000 km (3000 mi) and every 5000 km
(3000 mi) thereafter to indicate that the
engine oil should be changed.
After changing the engine oil, reset the
oil change tripmeter and the oil change
indicator. To reset them both, select
the oil change tripmeter, and then push
the “RES” button for one second.
Then, while “OIL” and the oil change
tripmeter are flashing, push the “RES”
button for three seconds. The oil
change indicator will be reset.
If the engine oil is changed before the
oil change indicator comes on (i.e., be-
fore the periodic oil change interval has
been reached), the oil change tripmeter
must be reset for the next periodic oil
change to be indicated at the correct
time.
Shift timin

The shift timing indicator light has four
settings which can be adjusted.  Flashing pattern: this function al-
lows you to choose whether or not
the indicator light will come on and
whether it should flash or stay on
when activated.
 Activation point: this function al-
lows you to select the engine
speed at which the indicator light
is activated.
 Deactivation point: this function
allows you to select the engine
speed at which the indicator light
is deactivated.1. Oil change indicator “OIL”

indicator light.
To adjust the shift timing indicator light
1. Turn the key to “ ”.
2. Push and hold the “SEL” button.
3. Turn the key to “ ”, and then re- lease the “SEL” button after five

To set the flashing pattern1. Push the “RES” button to select one of the following flashing pat-
tern settings: On: the indicator light stays
on when activated. (This set-
ting is selected when the indi-
cator light stays on.)
 Flash: the indicator light
flashes when activated. (This
setting is selected when the
indicator light flashes four
times per second.)
 Off: the indicator light is deac-
tivated; in other words, it
does not come on or flash. (This setting is selected when
the indicator light flashes
once every two seconds.)
2. Push the “SEL” button to confirm the selected flashing pattern. The
shift timing indicator light changes
to the activation point setting
mode.
The tachometer will show the current
setting r/min for the activation point
and deactivation point setting modes.
To set the shift activation point
TIPThe shift timing indicator light activa-
tion point can be set between 7000
r/min and 13500 r/min. From 7000
r/min to 12000 r/min, the indicator light
can be set in increments of 500 r/min.
From 12000 r/min to 13500 r/min, the
indicator light can be set in increments
of 200 r/min.1. Push the “RES” button to select the desired engine speed for acti-
vating the indicator light. 2. Push the “SEL” button to confirm
the selected engine speed. The
control mode changes to the de-
activation point setting mode.
To set the deactivation point
TIP The shift timing indicator light de-
activation point can be set be-
tween 7000 r/min and 13500
r/min. From 7000 r/min to 12000
r/min, the indicator light can be set
in increments of 500 r/min. From
12000 r/min to 13500 r/min, the in-
dicator light can be set in incre-
ments of 200 r/min.
 Be sure to set the deactivation
point to a higher engine speed
than for the activation point, other-
wise the shift timing indicator light
will not come on.1. Push the “RES” button to select
the desired engine speed for de-
activating the indicator light.
2. Push the “SEL” button to confirm the selected engine speed. The
control mode changes to the
brightness setting mode.

Fuel tank capTo open the fuel tank cap
Open the fuel tank cap lock cover, in-
sert the key into the lock, and then turn
it 1/4 turn clockwise. The lock will be
released and the fuel tank cap can be
opened.
To close the fuel tank cap1. Push the fuel tank cap into posi- tion with the key inserted in the
lock.
2. Turn the key counterclockwise to the original position, remove it,
and then close the lock cover.
TIPThe fuel tank cap cannot be closed un-
less the key is in the lock. In addition,
the key cannot be removed if the cap is
not properly closed and locked.
WARNING
EWA11092
Make sure that the fuel tank cap is
properly close d after fillin g fuel.
Leakin g fuel is a fire hazar d.
EAU13222
FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline an d g asoline vapors are
extremely flamma ble. To avoi d fires
an d explosions an d to re duce the
risk of injury when refuelin g, follow
these instructions.1. Before refueling, turn off the en- gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfill the fuel tank. When refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. Stop filling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine or
the sun can cause fuel to spill out
of the fuel tank.

4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
Gasoline is poisonous an d can
cause injury or d eath. Handle gaso-
line with care. Never siphon gasoline
b y mouth. If you shoul d swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some g asoline in
your eyes, see your doctor imme di- ately. If g
asoline spills on your skin,
wash with soap an d water. If gaso-
line spills on your clothin g, chan ge
your clothes.
EAU49743
NOTICE
ECA11401
Use only unlea ded g asoline. The use
of lead ed g asoline will cause severe
d amag e to internal en gine parts,
such as the valves an d piston rin gs,
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
95 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.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.

Sidestan dThe sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the vehicle upright.TIPThe built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situa-
tions. (See the following section for an
explanation of the ignition circuit cut-
off system.)

I g nition circuit cut-off systemThe ignition circuit cut-off system
(comprising the sidestand switch,
clutch switch and neutral switch) has
the following functions.
 It prevents starting when the
transmission is in gear and the
sidestand is up, but the clutch le-
ver is not pulled.
 It prevents starting when the
transmission is in gear and the
clutch lever is pulled, but the side-
stand is still down.
 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 accord-
ing to the following procedure.
