Checking method
Check with throttle fully closed.
Check with throttle fully open.
Set the engine stop switch to "RUN",
then operate the throttle while push-
ing the start switch. (If the display
value changes, the performance is
OK.)
Compare the actually measured
intake air temperature with the meter.
Compare the actually measured cool-
ant temperature with the meter.
Check that the number increases
when the rear wheel is rotated. The
number 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 "RUN",
and then compare with the actually
measured battery voltage. (If the bat-
tery voltage is lower, perform recharg-
ing.)
Shift the transmission.
