Be sure to stop the vehicle before
making any setting changes to the
multi-function meter unit. Changing
settings while riding can distract the
operator and increase the risk of an
accident.The multi-function meter unit is
equipped with the following:
a speedometera tachometer
a clock
a fuel meter
a coolant temperature meter
an odometer and tripmeter display
a multi-function display
a self-diagnosis device
TIPBe sure to turn the key to “ON” be-
fore using the “SELECT”, “RE-
SET” and “INFO” buttons.
When the key is turned to “ON”, all
display segments of the multi-
function meter unit will momen-
tarily appear in order to test the
electrical circuit. The speedome-
ter, tachometer, fuel meter and
coolant temperature meter will
then perform a display check and
a welcome message will scroll
across the multi-function display.
For the U.K. only: To switch the
speedometer and multi-function
displays between kilometers and
miles, press the “SELECT” and
“RESET” button together, turn the
key to “ON” and then release the

distance traveled since last set to
zero)
a fuel reserve tripmeter (which
shows the distance traveled since
the fuel level warning light came
on)
Pushing the “SELECT” button switch-
es the display between the odometer
mode and the various tripmeter modes
in the following order:
ODO (odometer) → TRIP 1 (tripmeter)
→ TRIP 2 (tripmeter) → ODO (odome-
ter)
When approximately 3.0 L (0.79 US
gal, 0.66 Imp.gal) of fuel remains in the
fuel tank, the display will automaticallychange to the fuel reserve tripmeter
mode “F TRIP” and start counting the
distance traveled from that point. In
that case, pushing the “SELECT” but-
ton switches the display between the
various tripmeter and odometer modes
in the following order:
ODO → TRIP 1 → TRIP 2 → F TRIP (fu-
el reserve tripmeter) → ODO
To reset a tripmeter, select it by push-
ing the “SELECT” button until “TRIP 1,
TRIP 2, F TRIP” is displayed. While
“TRIP 1, TRIP 2, F TRIP” is displayed,
push the “RESET” button for two sec-
onds. The fuel reserve tripmeter will re-
set automatically and disappear after
you have refueled and turned the key
to “OFF”.Multi-function display
The multi-function display is equipped
with the following:
a fuel consumption display (aver-
age and instantaneous consump-
tion functions)
an average speed display (which
shows the average speed since
last set to zero)
a time tripmeter (which shows the
elapsed riding time since last set
to zero)
 an oil change indicator with an oil
service reminder (which shows the
riding distance since last set to ze-
ro)
a low battery voltage warning indi-

3 Oil change indicator “OIL”
This indicator flashes (message “OIL
SERV” will also appear) to indicate that
the engine oil should be changed. It will
come on at the initial 1000 km (600 mi)
service interval, 2000 km (1200 mi) af-
ter that, and every 3000 km thereafter.
After changing the engine oil, reset the
oil change indicator.
To reset the oil change indicator dis-
play (mode “ODO” should be select-
ed), push the “RESET” button for two
seconds until “OIL SERV” message
flashes and then push and hold the
“RESET” button for at least 15 sec-
onds. “DIST SERV” mode (oil service
reminder which shows the riding dis-
tance since last reset) will also be reset.
TIPIf the engine oil is changed before the
oil change indicator comes on (i.e. be-
fore the set oil service interval has been
reached), the indicator must be reset
for the next oil change to be indicated
at the correct time. To reset the oil
change indicator before the periodic oil
change interval has been reached, fol-
low the below procedure.
To reset the oil change indicator (mode




SERVŽ mode flashes and then push


sage will also be reset.

Rev the engine freely through the
gears, but do not use full throttle at any
time. NOTICE: After 1000 km (600 mi)
of operation, the engine oil must be
changed, the oil filter cartridge or el-
ement replaced, and the oil strainer
cleaned.

ans or children are not likely to
touch them and be burned.
Do not park on a slope or on soft
ground, otherwise the vehicle
may overturn, increasing the
risk of a fuel leak and fire.

erosion and excessive carbon or
other deposits, and replace it if
necessary.
To install the spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifi-
cation.2. Clean the surface of the spark
plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then tight-
en it to the specified torque.
TIPIf a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4…
1/2 turn past finger tight. However, the
spark plug should be tightened to the
specified torque as soon as possible.4. Install the spark plug cap.
5. Install the cowling.

Engine oil and oil filter ele-
mentThe engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart.
To check the engine oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in), and then remove it
again to check the oil level.
NOTICE: Do not operate the ve-
hicle until you know that the en-
gine oil level is sufficient.

TIPThe engine oil should be between the
minimum and maximum level marks.
4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
5. Install the oil filler cap.
To change the engine oil (with or
without oil filter element replace-
ment)
1. Remove cowling D. (See page
6-8.)
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Install the engine oil drain attach-
ment, provided with the owner’s
tool kit, under the drain bolt of the
crankcase.4. Place an oil pan under the engine
to collect the used oil.
5. Remove the engine oil filler cap
and the drain bolt along with the
O-ring, compression spring, and
engine oil strainer, to drain the oil
from the crankcase. NOTICE:
When removing the engine oil
drain bolt, the O-ring, compres-
sion spring, and oil strainer will
fall out. Take care not to lose
these parts.
