open.
Turn On the engine stop
switch, then operate the
throttle while pressing the
start switch. (If the display
value changes, the perfor-
mance is OK.)
Compare the actually mea-
sured intake air tempera-
ture with the meter display
value. (*)
Compare the actually mea-
sured coolant temperature
with the meter display
value.
Check that the number
changes (integrating) when
the rear wheels are rotated.
Remove the lean angle
sensor and incline it more
than 65 degrees.
Compare with the actually
measured battery voltage.
(If the battery voltage is
lower, perform recharging.)
Turn ON/OFF the Sidestand
switch.
Perform the shift operation
of transmission.
