High beam indicator light “”
This indicator light comes on when the
high beam of the headlight is switched
on.
EAU11120
Oil level warning light “”
This warning light comes on when the
engine oil level is low.
The electrical circuit of the warning light
can be checked by turning the key to
“ON”.
If the warning light does not come on
for a few seconds, then go off, have a
Yamaha dealer check the electrical cir-
cuit.NOTE:Even if the oil level is sufficient, the
warning light may flicker when riding on
a slope or during sudden acceleration
or deceleration, but this is not a mal-function.
EAU27020
Immobilizer system indicator light
“”
The electrical circuit of the indicator
light can be checked by turning the key
to “ON”.
If the indicator light does not come on
for a few seconds, then go off, have a
Yamaha dealer check the electrical cir-
cuit.
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.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 when the key is turned to
“ON”. When this occurs, have a
Yamaha dealer check the self-diagno-
sis system. However, if the indicator
light slowly flashes five times, and then
quickly flashes two times repeatedly,this error could be caused by signal in-
terference. If this occurs, try the follow-
ing.
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
Yamaha dealer and have the stan-
dard keys re-registered.

WARNING
EWA10270
Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.
Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
Before starting out, make sure
that the sidestand is up. If the
sidestand is not raised com-
pletely, it could contact the
ground and distract the opera-
tor, resulting in a possible lossof control.
EAU36600
Starting a cold engine In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
The transmission is in the neutral
position.
The transmission is in gear with
the clutch lever pulled and the sid-
estand up.WARNING
EWA10290
Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-19.
Never ride with the sidestanddown.
1. Turn the fuel cock lever to “ON”.
2. Turn the key to “ON” and make
sure that the engine stop switch is
set to “”.
3. Shift the transmission into the neu-
tral position.
NOTE:When the transmission is in the neutral
position, the neutral indicator light
should be on, otherwise have a
Yamaha dealer check the electrical cir-cuit.
4. Turn the starter (choke) on and
completely close the throttle. (See
page 3-14.)
5. Start the engine by pushing the
start switch.NOTE:If the engine fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank the en-
gine more than 10 seconds on any oneattempt.CAUTION:
ECA15050
The oil level warning light
should come on when the key is
turned to “ON”, and then go off
after a few seconds. If the oil
level warning light flickers or re-
mains on after starting, immedi-

5 ately stop the engine, and then
check the engine oil level and
the vehicle for oil leakage. If
necessary, add engine oil, and
then check the warning light
again. If the warning light does
not come on when turning the
key to “ON”, or if it does not go
off after starting the engine with
sufficient engine oil, have a
Yamaha dealer check the elec-
trical circuit.
The immobilizer system indica-
tor light should come on when
the key is turned to “ON”, and
then go off after a few seconds.
If the indicator light does not
come on when the key is turned
to “ON”, then go off, have a
Yamaha dealer check the elec-trical circuit.
6. After starting the engine, move the
starter (choke) back halfway.
CAUTION:
ECA11040
For maximum engine life, never ac-
celerate hard when the engine iscold!7. When the engine is warm, turn the
starter (choke) off.
NOTE:The engine is warm when it responds
normally to the throttle with the starter(choke) turned off.
EAU16640
Starting a warm engine Follow the same procedure as for start-
ing a cold engine with the exception
that the starter (choke) is not required
when the engine is warm.

NOTE:
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
Hydraulic brake and clutch service
Regularly check and, if necessary, correct the brake and clutch fluid levels.
Every two years replace the internal components of the brake master cylinders and calipers as well as clutch master
and release cylinders, and change the brake and clutch fluids.Replace the brake and clutch hoses every four years and if cracked or damaged.

Checking the spark plugs The spark plugs are important engine
components, which are easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plugs should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
To remove a spark plug
1. Remove the spark plug cap.
2. Remove the spark plug as shown,
with the spark plug wrench includ-
ed in the owner’s tool kit.To check the spark plugs
1. Check that the porcelain insulator
around the center electrode on
each spark plug is a medium-to-
light tan (the ideal color when the
vehicle is ridden normally).
2. Check that all spark plugs installed
in the engine have the same color.
NOTE:If any spark plug shows a distinctly dif-
ferent color, the engine could be defec-
tive. Do not attempt to diagnose such
problems yourself. Instead, have aYamaha dealer check the vehicle.3. Check each spark plug for elec-
trode erosion and excessive car-
bon or other deposits, and replace
it if necessary.
To install a spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.

gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then tight-
en it to the specified torque.
NOTE:
If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-fied torque as soon as possible.
4. Install the spark plug cap.
EAU19691
Engine oil and oil filter
element The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart.
To check the engine oil level
1. Place the vehicle on the center-
stand.NOTE:
Make sure that the vehicle is positioned
straight up when checking the oil level.
A slight tilt to the side can result in afalse reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Wait a few minutes until the oil set-
tles, and then check the oil level
through the check window located
at the bottom-right side of the
crankcase.
NOTE:The engine oil should be between theminimum and maximum level marks.
4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
To change the engine oil (with or
without oil filter element replace-
ment)
1. Start the engine, warm it up for
several minutes, and then turn it
off.
