cuits.
If any of those circuits are defective, the
engine trouble warning light will come
on or flash, and then the odometer/trip-
meter display will indicate a two-digit
error code.

terference. If this error code appears,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

3curs, use a gasoline of a different brand
or premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.
EAU34072
Fuel tank breather/overflow
hose Before operating the motorcycle:

Check the fuel tank breather/over-
flow hose connection.


Check the fuel tank breather/over-
flow hose for cracks or damage,
and replace it if damaged.


Make sure that the end of the fuel
tank breather/overflow hose is not
blocked, and clean it if necessary.


Make sure that the end of the fuel
tank breather/overflow hose is po-
sitioned outside of the cowling.
EAU13442
Catalytic converters This vehicle is equipped with catalytic
converters in the exhaust system.
WARNING
EWA10860
The exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before do-ing any maintenance work.CAUTION:
ECA10700
The following precautions must be
observed to prevent a fire hazard or
other damages.

Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.


Never park the vehicle near pos-
sible fire hazards such as grass
or other materials that easily
burn.

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.


If the EXUP system cannot be
heard when the main switch is
turned on, have a Yamaha deal-er check it.
EAU15301
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.
