EAU11601
Speedometer The speedometer shows the riding
speed.
When the key is turned to “ON”, the
speedometer needle will sweep once
across the speed range and then return
to zero in order to test the electrical cir-
cuit.
EAU11872
Tachometer The electric tachometer allows the rider
to monitor the engine speed and keep it
within the ideal power range.
When the key is turned to “ON”, the ta-
chometer needle will sweep once
across the r/min range and then return
to zero r/min in order to test the electri-
cal circuit.CAUTION:
ECA10031
Do not operate the engine in the ta-
chometer red zone.Red zone: 9500 r/min and above
EAU11991
Self-diagnosis device This model is equipped with a self-diag-
nosis device for the following electrical
circuits:
throttle position sensor
speed sensor
If any of those circuits are defective, the
tachometer will repeatedly display the
following error code:
Use the table below to identify the faulty
electrical circuit.
If the tachometer displays such an error
code, note the circuit-specific number
of r/min, and then have a Yamaha deal-
er check the vehicle.
