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. See page 7-21
for tire specifications and for informa-
tion on servicing and 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.
 Shift the transmission into gear
(for models with a manual trans-
mission).
 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.

This warning light comes on when you
are low on fuel. When the fuel level
drops below approximately 3.4 L (0.90
US gal, 0.75 Imp.gal), the light will
come on to remind you to refuel as
soon as possible.
When the vehicle is turned on, the light
will perform a circuit check (come on
for a few seconds and then go off).

temperature display, stop the vehicle,
then stop the engine and let the engine
cool.
The electrical circuit of the warning
light can be checked by turning the ve-
hicle 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 vehicle is turned on,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.NOTICE

This indicator light will flash when trac-
tion control has engaged.
If the traction control system is turned
off, this indicator light will come on.

should come on for a few seconds and
then go off. If the light does not come
on, or if the light remains on, have a
Yamaha dealer check the vehicle.

Shift li ght
This light can be set to come on and go
off at select engine speeds. (See page
4-15.)TIPWhen the vehicle is turned on, the light
will come on for a few seconds and
then go off. If the light does not come
on, have a Yamaha dealer check the
vehicle.
EAU80300
Immo bilizer system in dicator li ght
When the key is turned to “OFF” and
30 seconds have passed, the indicator
light will flash steadily to indicate the
immobilizer 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”,
if the indicator light remains on, or if the
indicator light flashes in a pattern (if a
problem is detected in the immobilizer
system, the immobilizer system indica-
tor light will flash in a pattern), have a
Yamaha dealer check the vehicle.
TIPIf the immobilizer system indicator light
flashes in the pattern, slowly 5 times
then quickly 2 times, this could be
caused by transponder interference. If
this occurs, try the following.1. Make sure there are no other im- mobilizer keys close to the main
switch. Other immobilizer system
keys may cause signal interfer-
ence and prevent the engine from
starting.
2. Use the code re-registering key to start the engine.

EAU19653
Checkin g the spark plu gsThe 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.

En gine oil an d oil filter car-
tri dgeThe engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the en gine oil level
1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Wait a few minutes for the oil level to settle for an accurate reading.
4. Remove the engine oil dipstick and wipe it clean, insert it back
into the hole (without screwing it
in), and then remove it again to
check the oil level.TIPThe engine oil should be between the
minimum and maximum level marks.
5. Check the dipstick O-ring fordamage, and replace it if neces-
sary.
6. If the engine oil is at or below the minimum level mark, remove the
engine oil filler cap, and then add
sufficient oil of the recommended
type to raise it to the correct level. 7. Check the filler cap O-ring for
damage, and replace it if neces-
sary.
8. Insert and tighten the engine oil dipstick, and then install and tight-
en the oil filler cap.
To chan ge the en gine oil (with or
without oil filter cartri dge replace-
ment) 1. Place the vehicle on a level sur- face.
2. Remove cowlings A and B. (See page 7-9.)
