value.
Set the engine stop switch
to "
" then operate the
throttle while pushing the
start switch " ". (If the dis-
play value changes, the
performance is OK.)
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
