Check with throttle fully
closed.
Check with throttle fully
open.
Set the engine stop switch
to " ", and then push the
start switch " ". (If the dis-
play value changes, the
performance is OK.)
Compare the actually mea-
sured intake air tempera-
ture with the meter display
value. (*1)
Compare the actually mea-
sured coolant temperature
with the meter display val-
ue.
Check that the number in-
creases when the front
wheel is rotated.
The number is cumulative
and does not reset each
time the wheel is stopped.
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.)
Extend and retract the side-
stand.
