Procedure
Check the fully closed throt-
tle valve.
Check the fully opened throt-
tle valve.
Check the intake air pressure
when cranking the engine. (If
the displaying value chang-
es, the performance is OK.)
Compare the actually mea-
sured air temperature with
the tool displayed value.
Compare the actually mea-
sured coolant temperature
with the tool displayed 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 tool displayed value. (If
the actually measured bat-
tery voltage is low, recharge
the battery.)
Check the sidestand switch
condition.
