EAU00373
WARNING
_

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 loss
of control.
_
EAU04560
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
sidestand up.
EW000054
WARNING
_

Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-26.


Never ride with the sidestand
down.
_1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “”.

CAUTION:_ The following warning lights and in-
dicator light should come on for a
few seconds, then go off.

If a warning or indicator light does
not go off, see pages 3-2–3-5 for the
corresponding warning and indica-
tor 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.

EAU01880
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 col-
or when the motorcycle is ridden nor-
mally), and all spark plugs installed in
the engine should have the same color.
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.
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. Specified spark plug:
CR9E
IA 9 (NGK) or
IU27D (DENSO)

0.8–0.9 mm

6Clean 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. _
EAU04279
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 a level
surface and hold it in an upright
position.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:
12.5 Nm (1.25 m·kgf)1. Engine oil level check window

6 10. 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. _11. Turn the engine off, and then
check the oil level and correct it if
necessary.
12. Install the cowling.
EAU04298
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.
To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.
NOTE:_

The coolant level must be checked
on a cold engine since the level
varies with engine temperature.


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.
_2. Check the coolant level in the
coolant reservoir.NOTE:_ The coolant should be between the
minimum and maximum level marks. _3. If the coolant is at or below the min-
imum level mark, remove panel A
(See page 6-7 for panel removal
and installation procedures.), re-
move the reservoir cap, add cool-
ant to the maximum level mark,
and then install the reservoir cap
and the panel.
