Procedure
Operate the throttle while
pulling the brake lever and
pushing the start switch "
(If the display 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 in-
creases when the front wheel
is rotated. The number is cu-
mulative and does not reset
each time the wheel is
stopped.
Remove the lean angle sen-
sor and incline it more than
50 degrees.
Compare the actually mea-
sured battery voltage with
the meter display value. (If
the actually measured bat-
tery voltage is low, recharge
the battery.)
Extend and retract the side-
stand.
