Checking method
Check with throttle valves
fully closed.
Check with throttle valves
fully opened.
Compare the actually mea-
sured atmospheric pres-
sure with the meter display
value.
Compare the actually mea-
sured atmospheric pres-
sure with the meter display
value without cranking the
engine.
Compare the actually mea-
sured 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
sensor and incline it more
than 65 degrees.
Set the engine stop switch
to " ", and then compare
with the actually measured
battery voltage. (If the bat-
tery voltage is lower,
recharge the battery.)
