EAU00083
Fuel level warning light “ ”
This warning light comes on when the
fuel level drops below approximately
3 L. When this occurs, set the fuel re-
serve switch to the “RES” position and
refuel as soon as possible.
EAU00063
High beam indicator light “ ”
This indicator light comes on when the
high beam of the headlight is switched
on.
EAU03285
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 according to the fol-
lowing procedure.
1. Turn the key to “ON”.
2. If the warning light does not come
on, have a Yamaha dealer check
the electrical circuit.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. @
EAU00095
Speedometer unit The speedometer unit is equipped with
a speedometer, an odometer and a
tripmeter. The speedometer shows
riding speed. The odometer shows the
total distance traveled. The tripmeter
shows the distance traveled since it
was last set to zero with the reset knob.
The tripmeter can be used to estimate
the distance that can be traveled with a
full tank of fuel. This information will en-
able you to plan future fuel stops.1. Tripmeter reset knob

5-OPERATION AND IMPORTANT RIDING POINTS
EAU00373
WARNING
@ l
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.
l
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.
l
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 loss
of control.
@
EAU01627
Starting a cold engine In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:l
The transmission is in the neutral
position.
l
The transmission is in gear with
the clutch lever pulled and the
sidestand up.
EW000054
WARNING
@ l
Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-16.
l
Never ride with the sidestand
down.
@1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “ ”.
EC000035
CAUTION:@ If the fuel level warning light comes
on, check the fuel level, and, if nec-
essary, refuel as soon as possible. @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. Turn the starter (choke) on and
completely close the throttle. (See
page 3-8 for starter (choke) opera-
tion.)
4. 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 one
attempt. @
EC000038
CAUTION:@ l
The oil level warning light and
fuel level warning light should
come on when the start switch
is pushed, and they should go
off when the start switch is re-
leased.
l
If the oil level warning light flick-
ers or remains on after starting,
immediately stop the engine,
and then check the engine oil
level and the vehicle for oil leak-
age. If necessary, add engine
oil, and then check the warning
light again. If the warning light
does not come on when push-
ing the start switch, or if it doesnot go off after starting with suf-
ficient engine oil, have a
Yamaha dealer check the elec-
trical circuit.
l
If the fuel level warning light re-
mains on after starting, stop the
engine, and then check the fuel
level. If necessary, refuel as
soon as possible, and then
check the warning light again. If
the warning light does not come
on when pushing the start
switch, or if it does not go off af-
ter starting with sufficient fuel,
have a Yamaha dealer check the
electrical circuit.
@5. After starting the engine, move the
starter (choke) lever back halfway.
ECA00045
CAUTION:@ For maximum engine life, never ac-
celerate hard when the engine is
cold! @
6. 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. @

6 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
motorcycle 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 a
Yamaha dealer check the motorcycle. @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.
2. Clean the surface of the spark
plug gasket and its mating sur-
face, 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.
1. Spark plug wrench
Specified spark plug:
DPR8EA-9/NGK or
X24EPR-U9/DENSO

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.
EAU02938
Engine oil and oil filter
cartridge 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 motorcycle on the cen-
terstand.NOTE:@ Make sure that the motorcycle is posi-
tioned straight up when checking the oil
level. 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 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 the
minimum 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. Tightening torque:
Spark plug:
18 Nm (1.8 m·kg)1. Engine oil level check window

CAUTION:@ l
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives with
the oil or use oils of a higher
grade than “CD”. In addition, do
not use oils labeled “ENERGY
CONSERVING II” or higher.
l
Make sure that no foreign mate-
rial enters the crankcase.
@9. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.NOTE:@ After the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient. @
EC000067
CAUTION:@ If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha deal-
er check the vehicle. @10. Turn the engine off, and then
check the oil level and correct it if
necessary.

Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
If the engine overheats, see page 6-46
for further instructions.
To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.
2. Remove cowling A. (See page 6-6
for cowling removal and installa-
tion procedures.)
NOTE:@ l
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
l
Make sure that the motorcycle is
positioned straight up when
checking the coolant level. A slight
tilt to the side can result in a false
reading.
@3. Check the coolant level in the
coolant reservoir.NOTE:@ The coolant should be between the
minimum and maximum level marks. @4. If the coolant is at or below the
minimum level mark, remove the
coolant reservoir cap and add
coolant to the maximum level
mark.
5. Install the coolant reservoir cap
and the cowling.
1. Maximum level mark
2. Minimum level mark
