Checking method
Check with throttle valves
fully closed.
Check with throttle valves
fully open.
Compare the actually mea-
sured atmospheric pressure
with the meter display
value.
Set the engine stop switch
to " ", and then push the
start switch " ". (If the dis-
play value changes, the per-
formance is OK.)
Compare the actually mea-
sured intake air temperature
with the meter display
value.
Compare the actually mea-
sured coolant temperature
with the meter display
value.
Check that the number
increases when the rear
wheel is rotated. The num-
ber is cumulative and does
not reset each time the
wheel is stopped.
Remove the lean angle sen-
sor and incline it more than
45 degrees.
Set the engine stop switch
to " ", and then compare
with the actually measured
battery voltage. (If the bat-
tery voltage is lower, per-
form recharging.)
Check with throttle valves
fully closed.
Check with throttle valves
fully open.
