This model is equipped with a self-di-
agnosis device for the following electri-
cal circuits:
G throttle position sensor
G speed sensor
G
EXUP system
3
G
overturn switch
If any of those circuits are defective,
the tachometer will repeatedly display
the following error code:
CB-23E
Circuit-specific
0 r/min for
number of r/min
3 seconds
for 2.5 seconds
(See the table
below.)
Use the chart below to identify the
faulty electrical circuit.
CB-29E
Specific r/min Faulty electrical circuit
3,000 r/min Throttle position sensor
4,000 r/min Speed sensor
7,000 r/min EXUP system
9,000 r/min Overturn switch
EAU04290 If the tachometer displays such an er-
ror code, note the circuit-specific num-
ber of r/min, and then have a Yamaha
dealer check the motorcycle.
CAUTION:
_
When the tachometer displays an
error code, the motorcycle should

1. Fuel gauge

Fuel gauge
The fuel gauge indicates the amount of
fuel in the fuel tank. The needle moves
towards "E" (Empty) as the fuel level
decreases. When the needle reaches
"E", approximately 4 L (0.9 Imp gal,
1.1 US gal) of fuel remain in the fuel
tank. If this occurs, refuel as soon as
possible.
NOTE:
_
Do not allow the fuel tank to empty it-
self completely.
