High beam indicator light “1”
This indicator light comes on when the
high beam of the headlight is switched on.
EAUB0002
Fuel level warning light “K”
This warning light comes on when the fuel
level drops below approximately 5.8 L.
When this occurs, refuel as soon as possi-
ble.
The electrical circuit of the warning light
can be checked according to the following
procedure.
1. Turn the key to “
I” (ON).
2. If the warning light does not come on,
have a Yamaha dealer check the
electrical circuit.
NOTE:
This model is equipped with a self-diagno-
sis device for the fuel level warning light
circuit. (See page 3-6 for an explanation of
the self-diagnosis device).

Speedometer unit
The speedometer unit is equipped with the
following:
•a speedometer (which shows riding
speed)
•a tachometer (which shows engine
r/min)
•an odometer (which shows the total
distance traveled)
1. Speedometer set to km/h
2. Tachometer
3. Odometer/ tripmeter/ fuel reserve tripmeter/
clock display
4. “SET” button
5. “RESET” button
•two tripmeters (which show the dis-
tance traveled since they were last
set to zero)
•a fuel reserve tripmeter (which shows
the distance traveled on the fuel re-
serve)
•an oil change indicator (which is dis-
played when the oil needs to be
changed)
•a clock.

INSTRUMENT AND CONTROL FUNCTIONS
NOTE:
Depending on the market where the
motorcycle is sold, the speedometer can
be set to either mph or km/h. When the
speedometer is set to mph, the odometer
counts in miles (1 mile = 1.61 km).Odometer and tripmeter modes
Pushing the “SET” button switches the dis-
play between the odometer mode “ODO”
and the tripmeter modes “TRIP 1” and
“TRIP 2” in the following order: ODO 6
TRIP 1 6TRIP 2 6ODO
When the fuel warning light comes on, the
display will automatically change to the fu-
el reserve tripmeter mode “TRIP F” and
start counting the distance traveled from
that point. In that case, pushing the “SET”
button switches the display between the
various tripmeter and odometer modes in
the following order: TRIP F 6TRIP 1 6
TRIP 2 6ODO 6TRIP F
To reset a tripmeter, select it by pushing
the “SET” button, and then push the “RE-
SET” button for at least one second. If you
do not reset the fuel reserve tripmeter
manually, it will reset itself automatically
and the display will return to the prior
mode after refueling and traveling several
kilometers.Oil change indicator
At the initial 1,000 km (620 mi) and every
10,000 km (6,200 mi) thereafter, the mes-
sage “OIL CHANGE” appears in the dis-
play for a few seconds when the key is
turned to “ON”, to indicate that the engine
oil should be changed.
After changing the engine oil, reset the oil
change indicator.
If the engine oil is changed before the oil
change indicator appears in the display
(i.e. before the periodic oil change interval
has been reached), the indicator must be
reset after the oil change for the next peri-
odic oil change to be indicated at the cor-
rect time.
NOTE:
When the message “OIL CHANGE”
appears in the display, be sure to change
the engine oil as soon as possible. In addi-
tion to these kilometer-based oil changes,
be sure to have a Yamaha dealer perform
the annual checks specified in the period-
ic maintenance and lubrication chart on
page 6-2.

Fuel tank breather hose
Before operating the motorcycle:
Check the fuel tank breather hose connec-
tion.
Check the fuel tank breather hose for

aged.
Make sure that the end of the fuel tank
breather hose is not blocked, and clean it if
necessary.

4. Start the engine by pushing the start
switch.
NOTE:
If the engine fails to start, release the start
switch, wait a few seconds, and then try

short as possible to preserve the battery.
Do not crank the engine more than 10 sec-
onds on any one attempt.

The oil level warning light and fuel lev-
el warning light should come on when
the start switch is pushed, and they
should go off when the start switch is
released.
If the oil level warning light flickers or
remains on after starting, immediately
stop the engine, and then check the
engine oil level and the vehicle for oil
leakage. If necessary, add engine oil,
and then check the warning light again.
If the warning light does not come on
when pushing the start switch, or if it
does not go off after starting with suffi-
cient engine oil, have a Yamaha dealer
check the electrical circuit.
If the fuel level warning light remains
on after starting, stop the engine, and
then check the fuel level. If necessary,
refuel as soon as possible, and then
check the warning light again. If the
warning light does not come on when
pushing the start switch, or if it does
not go off after starting with sufficient
fuel, have a Yamaha dealer check the
electrical circuit.
CAUTION:5. After starting the engine, move the
starter (choke) knob/lever back
halfway.
ECA00045
For maximum engine life, never accel-
erate hard when the engine is cold!
6. When the engine is warm, turn the
starter (choke) off.
NOTE:
The engine is warm when it responds nor-
mally to the throttle with the starter (choke)
turned off.
