3 Instantaneous fuel consumption
meter
This meter shows the instantaneous
fuel consumption.
Depending on the display setting se-
lected for the instantaneous fuel con-
sumption mode “F/ECO”, the
displayed segments increase or de-
crease.
 km/L and MPG (for the UK): The
number of segments displayed in-
creases the more efficiently the
vehicle is being operated.
 L/100 km: The number of seg-
ments displayed decreases the
more efficiently the vehicle is be-
ing operated.
Multi-function display
The multi-function display is equipped
with the following: 
an odometer
 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 last segment of the fuel meter
started flashing)
 an instantaneous fuel consump-
tion display
 an average fuel consumption dis-
play
 an oil change tripmeter
 a V-belt replacement tripmeter

indicator will be displayed.
Oil chan ge tripmeter mo de
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), and ev-
ery 6000 km (3500 mi) thereafter to in-
dicate 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 “RESET” button for one second.
Then, while “OIL” and the oil change
tripmeter are flashing, push the “RE-
SET” 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.

g
1. Clean the surface of the spark plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.
2. Install the spark plug with the spark plug wrench, and then tight-
en it to the specified torque.
TIP
If 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.
3. Install the spark plug cap.
TIP
Install the spark plug cap so that it is
positioned as shown in the illustration
and the spark plug lead does not con-
tact any surrounding parts.
4. Install the panels.

Engine oil an d oil strainer
The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil strainer
cleaned at the intervals specified in the
periodic maintenance and lubrication
chart.
To check the en gine oil level
1. Place the vehicle on the center- stand. 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 engine oil filler
cap, wipe the engine oil dipstick
clean, insert it back into the oil filler
hole (without screwing it in), and
then remove it again to check the
oil level. WARNING! The muffler
an d muffler protector become
very hot d uring use. To avoi d
possi ble burns, let the muffler
an d protector cool b efore re-
moving the oil filler cap.
