Displays the intake air pres-
sure.
When engine is cold: Dis-
plays temperature closer to
air temperature
When engine is hot: Air tem-
perature + approx. 20°C (68
°F)
When engine is cold: Dis-

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.
Rear wheel stops: make
sure that the indication
value is constant.
Rotate the rear wheel by
hand several times to enter
the rear wheel vehicle
speed pulses: the indication
value is added.
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.)
