High beam indicator light “”
This indicator light comes on when the
high beam of the headlight is switched
on.
EAU03201
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. Set the engine stop switch to “”
and turn the key to “ON”.
2. Shift the transmission into the neu-
tral position or pull the clutch lever.
3. Push the start switch. If the warn-
ing light does not come on while
pushing the start switch, have a
Yamaha dealer check the electri-
cal 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. @
EAU00094
Speedometer unit (for XJ600S) 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 but-
ton. The tripmeter can be used to esti-
mate the distance that can be traveled
with a full tank of fuel. This information
will enable you to plan future fuel stops.

5-OPERATION AND IMPORTANT RIDING POINTS
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
understand.


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.
@
EAU00381*
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 3-17.


Never ride with the sidestand
down.
@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
circuit. @4. Turn the starter (choke) on and
completely close the throttle. (See
page 3-12 for starter (choke) oper-
ation.)
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 one
attempt. @

EC000034
CAUTION:@ The oil level warning light should
come on when the start switch is
pushed, and it should go off when
the start switch is released. If the oil
level warning light flickers or re-
mains on after starting, immediately
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 pushing the start
switch, or if it does not go off after
starting with sufficient engine oil,
have a Yamaha dealer check the
electrical circuit. @6. 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! @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. @
EAU01258
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 service
Regularly check and, if necessary, correct the brake fluid level.
Every two years replace the internal components of the brake master cylinders and calipers, and change the brake
fluid.
Replace the brake hoses every four years and if cracked or damaged.

1. Place the panel in the original po-
sition, and then install the screws.
2. Install the seat.
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.a. Spark plug gap
Specified spark plug:
CR8E (NGK) or
U24ESR-N (DENSO)
Spark plug gap:
0.7–0.8 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. @
EAU04185
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:
12.5 Nm (1.25 m·kgf)

CAUTION:_

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.


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.
EAU02928*
Cleaning the air filter element The air filter element should be cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
Clean the air filter element more fre-
quently if you are riding in unusually
wet or dusty areas.
1. Remove the seat. (See page 3-12
for seat removal and installation
procedures.)
2. Turn the fuel cock lever to “ON”,
and then remove the fuel cock le-
ver by removing the screw.1. Screw
