EAU11080
High beam indicator light “”
This indicator light comes on when the
high beam of the headlight is switched
on.
EAU11361
Fuel level warning light “”
This warning light comes on when the
fuel level drops below approximately
3.0 L (0.79 US gal) (0.66 Imp.gal).
When this occurs, refuel as soon as
possible.
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, and then go off,
have a Yamaha dealer check the elec-
trical circuit.NOTE:This model is also equipped with a self-
diagnosis device for the fuel level de-
tection circuit. If the fuel level detection
circuit is defective, the following cycle
will be repeated until the malfunction is
corrected: The fuel level warning lightwill flash eight times, and then go off for
3.0 seconds. If this occurs, have a
Yamaha dealer check the vehicle.
EAU11530
Engine trouble warning light “”
This warning light comes on or flashes
when an electrical circuit monitoring the
engine is defective. When this occurs,
have a Yamaha dealer check the self-
diagnosis system. (See page 3-5 for an
explanation of the self-diagnosis de-
vice.)
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
circuit.
EAU38620
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.
This model is also equipped with a self-
diagnosis device for the immobilizer
system. (See page 3-5 for an explana-
tion of the self-diagnosis device.)

EAU15950
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.
EAU36740
Starting the 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 key to “ON” and make
sure that the engine stop switch is
set to “”.
CAUTION:
ECA15070
The following warning lights and in-
dicator light should come on for a
few seconds, then go off.

Fuel level warning light


Engine trouble warning light


Immobilizer system indicator
light
If a warning or indicator light does
not go off, see page 3-3 for the corre-
sponding warning and indicator
light circuit check.
2. 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.
3. 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.

EAU16810
Tips for reducing fuel con-
sumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:

Shift up swiftly, and avoid high en-
gine speeds during acceleration.


Do not rev the engine while shifting
down, and avoid high engine
speeds with no load on the engine.


Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
EAU16841
Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU17111
0–1000 km (0–600 mi)
Avoid prolonged operation above 2500
r/min.
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 3000
r/min.
CAUTION:
ECA10891
After 1000 km (600 mi) of operation,
the engine oil and transfer case oil
must be changed, and the oil filtercartridge or element replaced.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.CAUTION:
ECA10310


Keep the engine speed out of
the tachometer red zone.


If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-cle.

PERIODIC MAINTENANCE AND MINOR REPAIR

EAU19642
Checking the spark plugs The spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they 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.
The porcelain insulator around the cen-
ter 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 en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode
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.
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.
Specified spark plug:
NGK/DPR8EA-9
DENSO/X24EPR-U9
1. Spark plug gap
Spark plug gap:
0.8–0.9 mm (0.031–0.035 in)
Tightening torque:

EAU38361
Engine oil and oil filter car-
tridge The 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 engine oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.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. Remove the rider seat. (See page
3-14.)
3. Start the engine, warm it up until
the engine oil has reached a nor-
mal temperature of 60 °C (140 °F),
let it continue to idle for ten sec-
onds, and then turn the engine off.
NOTE:To achieve the proper engine oil tem-
perature for an accurate oil level read-
ing, the engine must have first
completely cooled down, and then
warmed up again for several minutes tonormal operating temperature.
4. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in), and then remove it
again to check the oil level.NOTE:The engine oil should be between theminimum and maximum level marks.5. If the engine oil is at or below the
minimum level mark, add sufficient
oil of the recommended type to
raise it to the correct level.
NOTE:When adding oil, be careful not to over-
fill the engine oil tank; the oil level rises
faster starting from the half level portionon the dipstick.
6. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
7. Install the rider seat.
