Tool display Procedure
Check with throttle valves ful-
ly closed.
Check with throttle valves ful-
ly open.
Compare the actually mea-
sured atmospheric pressure
with the tool display value.
Operate the throttle while
pushing the " " side of the
start/engine stop switch. (If
the display value changes,
the performance is OK.)
Compare the actually mea-
sured air temperature with
the tool display value.
Compare the actually mea-
sured coolant temperature
with the tool display value.
Check that the number in-
creases when the rear wheel
is rotated. The number is cu-
mulative and does not reset
each time the wheel is
stopped.
Set the start/engine stop
switch to " ", and then com-
pare the actually measured
battery voltage with the tool
display value. (If the actually
measured battery voltage is
low, recharge the battery.)
Check with throttle valves ful-
ly closed.
Check with throttle valves ful-
ly open.
Check with throttle grip fully
closed position.
Check with throttle grip fully
open position.
