SAFETY INFORMATION

1operator and may limit control
ability, therefore, such accesso-
ries are not recommended.
 Use caution when adding electri-
cal accessories. If electrical ac-
cessories exceed the capacity of
the motorcycle’s electrical sys-
tem, an electric failure could re-
sult, which could cause a
dangerous loss of lights or engine
power.
Aftermarket Tires an d Rims
The tires and rims that came with your
motorcycle were designed to match
the performance capabilities and to
provide the best combination of han-
dling, braking, and comfort. Other
tires, rims, sizes, and combinations
may not be appropriate. Refer to page
6-18 for tire specifications and more in-
formation on replacing your tires.
Transportin g the Motorcycle
Be sure to observe following instruc-
tions before transporting the motorcy-
cle in another vehicle.  Remove all loose items from the
motorcycle. 
Check that the fuel cock (if
equipped) is in the “OFF” position
and that there are no fuel leaks.
 Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
 Shift the transmission in gear (for
models with a manual transmis-
sion).
 Secure the motorcycle with tie-
downs or suitable straps that are
attached to solid parts of the mo-
torcycle, such as the frame or up-
per front fork triple clamp (and not,
for example, to rubber-mounted
handlebars or turn signals, or
parts that could break). Choose
the location for the straps carefully
so the straps will not rub against
painted surfaces during transport.
 The suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the mo-
torcycle will not bounce exces-
sively during transport.

The electrical circuit of the warning
light can be checked by turning the key
to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on
initially when the key is turned to “ON”,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.
TIP Even if the oil level is sufficient, the
warning light may flicker when rid-
ing on a slope or during sudden
acceleration or deceleration, but
this is not a malfunction.
 This model is also equipped with a
self-diagnosis device for the oil
level detection circuit. If a problem
is detected in the oil level detec-
tion circuit, the following cycle will
be repeated until the malfunction
is corrected: The oil level warning
light will flash ten times, then go
off for 2.5 seconds. If this occurs,
have a Yamaha dealer check the
vehicle.

Engine trou ble warnin g lig ht “ ”
This warning light comes on or flashes
if a problem is detected in the electrical
circuit monitoring the engine. If this oc-
curs, have a Yamaha dealer check the
self-diagnosis system. (See page 3-10
for an explanation of the self-diagnosis
device.)
The electrical circuit of the warning
light can be checked by turning the key
to “ON”. The warning light should
come on for a few seconds, and then

ABS warnin g li ght “ ” (for ABS
mo dels)
In normal operation, the ABS warning
light comes on when the key is turned
to “ON”, and goes off after traveling at
a speed of 10 km/h (6 mi/h) or higher.
If the ABS warning light:  does not come on when the key is
turned to “ON” 
comes on or flashes while riding
 does not go off after traveling at a
speed of 10 km/h (6 mi/h) or high-
er
The ABS may not work correctly. If any
of the above occurs, have a Yamaha
dealer check the system as soon as
possible. (See page 3-14 for an expla-
nation of the ABS.)

TIPIf the start switch is pushed while the
engine is running, the ABS warning
light will come on, but this is not a mal-
function.
EAU38626
Immo bilizer system in dicator li ght
When the key is turned to “OFF” and
30 seconds have passed, the indicator
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.
The electrical circuit of the indicator
light can be checked by turning the key
to “ON”. The indicator light should
come on for a few seconds, and then
go off.
If the indicator light does not come on
initially when the key is turned to “ON”,
or if the indicator light remains on, have
a Yamaha dealer check the electrical
circuit.
The self-diagnosis device also detects
problems in the immobilizer system
circuits. (See page 3-10 for an expla-
nation of the self-diagnosis device.)

Fuel meter
The fuel meter indicates the amount of
fuel in the fuel tank. The display seg-
ments of the fuel meter disappear to-
wards “E” (Empty) as the fuel level
decreases. When the last segment on
the left starts flashing, refuel as soon as
possible.
TIPThis fuel meter is equipped with a self-
diagnosis system. If a problem is de-
tected in the electrical circuit, the fol-
lowing cycle is repeated until the
malfunction is corrected: fuel level seg-
ments and symbol “ ” flash eight times, then go off for approximately 3
seconds. If this occurs, have a Yamaha
dealer check the electrical circuit.

Self-d iagnosis device
This model is equipped with a self-di-
agnosis device for various electrical
circuits.
If a problem is detected in any of those
circuits, the engine trouble warning
light will come on and the display will
indicate an error code.
If the display indicates any error codes,
note the code number, and then have
a Yamaha dealer check the vehicle.
The self-diagnosis device also detects
problems in the immobilizer system
circuits.

lizer system circuits, the immobilizer
system indicator light will flash and the
display will indicate an error code.
TIPIf the display indicates error code 52,
this could be caused by transponder
interference. If this error code appears,
try the following.1. Use the code re-registering key to
start the engine.TIPMake 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 engine
from starting.2. If the engine starts, turn it off andtry 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
Yamaha dealer and have the stan-
dard keys re-registered.

Place the panel in the original position,
and then install the bolt.
EAU19653
Checkin
g the spark plug sThe spark plugs are important engine
components, which should be
checked periodically, preferably by a
Yamaha dealer. Since heat and depos-
its will cause any spark plug to slowly
erode, they should be removed and
checked in accordance with the peri-
odic maintenance and lubrication
chart. In addition, the condition of the
spark plugs can reveal the condition of
the engine.
The porcelain insulator around the
center electrode of each spark plug
should be a medium-to-light tan (the
ideal color when the vehicle is ridden
normally), and all spark plugs installed
in the engine should have the same
color. If any spark plug shows a dis-
tinctly different color, the engine could
be operating improperly. Do not at-
tempt to diagnose such problems
yourself. Instead, have a Yamaha deal-
er check the vehicle.
If a spark plug shows signs of elec-
trode erosion and excessive carbon or
other deposits, it should be replaced. Before installing a spark plug, the
spark plug gap should be measured
with a wire thickness gauge and, if
necessary, adjusted to specification.
Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the spark
plug threads.
