light will start flashing indicating the im-
mobilizer system is enabled. After 24
hours have passed, the indicator light
will stop flashing, however the immobi-
lizer system is still enabled.NOTE:This model is also equipped with a self-
diagnosis device for the immobilizer
system. If the immobilizer system is de-
fective, the indicator light will start flash-
ing a pattern and the
odometer/tripmeter will display a 2-digit
code when the key is turned to “ON”.When this occurs, have a Yamaha
dealer check the self-diagnosis system.

flashes five times, and then quickly
flashes two times repeatedly, error
code 52 will be displayed. This error
could be caused by signal interference.
If this occurs, try the following.
1. Use the code re-registering key to
start the engine.NOTE:Make sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobilizer
key on the same key ring! Immobilizer
system keys may cause signal interfer-
ence, which may prevent the enginefrom starting.
2. If the engine starts, turn it off, and
try starting the engine with the
standard keys.
3. If one or both of the standard keys
do not start the engine, take the
vehicle, the code re-registering
key and both standard keys to a

EXUP system This model is equipped with Yamaha’s
EXUP (EXhaust Ultimate Power valve)
system. This system boosts engine
power by means of a valve that regu-
lates the diameter of the exhaust pipe.
The EXUP system valve is constantly
adjusted in accordance with the engine
speed by a computer-controlled servo-
motor.CAUTION:
ECA10191


The EXUP system has been set
and extensively tested at the
Yamaha factory. Changing
these settings without sufficient
technical knowledge may result
in poor performance of or dam-
age to the engine.

Sidestand The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle upright.NOTE:The built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See further down for an explanation ofthe ignition circuit cut-off system.)
WARNING
EWA10240
The vehicle must not be ridden with
the sidestand down, or if the side-
stand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly as describedbelow and have a Yamaha dealer re-
pair it if it does not function proper-
ly.
