INSTRUMENT FUNCTIONS
Multi-function display
The multi-function meter unit is equipped with
the following:
a speedometer (which shows the riding
speed)
a tachometer (witch shows engine speed)
an odometer (which shows the total distance
traveled)
two tripmeters (which show the distance
traveled since they were last set to zero)
a fuel reserve tripmeter (which shows the
distance traveled since the fuel level warning
light came on)
a stopwatch
a clock
a coolant temperature display
an air intake temperature display
a self-diagnosis device
a display brightness and shift timing indicator
light control mode
Be sure to turn the key to “ON” before using the “SELECT” and “RESET” buttons.
Clock mode
Turn the key to “ON”.
To set the clock
1. Push the “SELECT” button and “RESET”
button together for at least two seconds.
2. When the hour digits start flashing, push the
“RESET” button to set the hours.
3. Push the “SELECT” button, and the minute
digits will start flashing.
4. Push the “RESET” button to set the minutes.
5. Push the “SELECT” button and then release
it to start the clock.

NOTE:
NOTE:Odometer, tripmeter, and stopwatch modes
Push the “SELECT” button to switch the display
between the odometer mode “ODO”, the trip-
meter modes “TRIP A” and “TRIP B” and the
stopwatch mode in the following order:
TRIP A TRIP B ODO Stopwatch
TRIP A
If the fuel level warning light comes on, the
odometer display will automatically change to
the fuel reserve tripmeter mode ”F-TRIP” and
start counting the distance traveled from that
point. In that case, push the ”SELECT” button to
switch the display between the various tripme-
ter, odometer, and stopwatch modes in the fol-
lowing order:
F-TRIP Stopwatch TRIP A TRIP B
ODO F-TRIP
To reset a tripmeter, select it by pushing the “SE-
LECT” button, and then push the “RESET” button
for at least one second. If you do not reset the fuel
reserve tripmeter manually, it will reset itself auto-
matically and the display will return to the prior
mode after refueling and traveling 5 km (3 mi).
Stopwatch mode
Standard measurement
1. Push the “RESET” button to start the stopwatch.
2. Push the “SELECT” button to stop the stopwatch.
3. Push the “SELECT” button again to reset the stopwatch.
Split-time measurement
1. Push the “RESET” button to start the stopwatch.
2. Push the “RESET” button to measure split-times. (The colon “:” will start flashing.)
3. Push the “RESET” button to display the final split-time or push the “SELECT” button to stop the stop-
watch and display total elapsed time.
4. Push the “SELECT” button to reset the stopwatch.
Coolant temperature display
The coolant temperature display indicates the temperature of the coolant. Push the “RESET” button to
switch the coolant temperature display to the air intake temperature display.
When the coolant temperature display is selected, “C” is displayed before the coolant temperature.
Air intake temperature display
The air intake temperature display indicates the temperature of the air drawn into the air filter case. Push
the “RESET” button to switch the coolant temperature display to the air intake temperature display.
Even if the air intake temperature is set to be displayed, the coolant temperature warning light comes
on when the engine overheats.
When the key is turned to “ON”, the coolant temperature is automatically displayed, even if the air
intake temperature was displayed prior to turning the key to “OFF”.
When the air intake temperature display is selected, “A” is displayed before thetemperature.

the clamp.
D To the EXUP servo motor
E Pass the coolant reservoir tank
drain hose and fuel tank drain
hose through the clamp from the
outer side of the water pump inlet
pipe after routing it behind the
water pump breather hose.
The lengths of two hose ends are
allowed to be random. Any direc-
tion of cut edges can be ac-
cepted. (Only for the fuel tank
drain hose)
F Clamp the fuel tank drain hose
and fuel tank breather hose.A Clamp the leads so that they are
positioned inner of the vehicle
than the washer position after
routing them between the frame
and radiator stay. Align the clamp
position with the taping sections
of leads. Point the tip of the clamp
(surplus section) to the down
front side of the vehicle.
What the clamp fastens at this
stage are the handlebar switch
and main switch leads.
B Pass the main switch lead and
left handlebar switch lead be-
tween the frame and the heat
protector.
