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:@ l
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 malfunction.
l
This model is equipped with a self-
diagnosis device for the oil level
warning light circuit. (See page 3-8
for an explanation of the self-diag-
nosis device.)

4-PRE-OPERATION CHECKSThe condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, to check the following points before each ride.
EAU00340
PRE-OPERATION CHECK LIST

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:@ l
The engine is warm when it re-
sponds normally to the throttle
with the starter (choke) turned off.
l
When the engine is idling with the
starter (choke) turned on, the radi-
ator fan will automatically be
switched on and off regardless of
the coolant temperature. As a re-
sult, the engine idling speed will
vary, but this does not indicate a
malfunction.

The annual checks must be performed once a year, regardless of the mileage traveled.
l
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.

• Regularly check and, if necessary, correct the brake fluid level.
• Every two years replace the internal components of the brake master cylinder and caliper, and change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.

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.
@11. 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. @12. Turn the engine off, and then
check the oil level and correct it if
necessary.
13. Install the cowling stay by install-
ing the bolt.
14. Install the cowling.
EAU03161
Coolant To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.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.

coolant reservoir.
NOTE:@ The coolant should be between the
minimum and maximum level marks. @3. If the coolant is at or below the
minimum level mark, open the res-
ervoir cap, add coolant to the max-
imum level mark, and then close
the reservoir cap.
EC000080
CAUTION:@ l
If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.
l
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the cool-
ing system will not be protected
against frost and corrosion.
l
If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.
@
NOTE:@ l
The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.
l
When the engine is idling with the
starter (choke) turned on, the radi-
ator fan will automatically be
switched on and off regardless of
the coolant temperature, but this
does not indicate a malfunction.

If the engine overheats, see page
6-44 for further instructions.

To change the coolant
1. Place the motorcycle on a level
surface and let the engine cool if
necessary.
2. Remove cowlings A and B, and
panel A. (See pages 6-5 and 6-6
for cowling and panel removal and
installation procedures.)
3. Place a container under the en-
gine to collect the used coolant.4. Remove the radiator cap and cool-
ant reservoir cap.

WARNING
@ Never attempt to remove the radia-
tor cap when the engine is hot. @5. Remove the coolant reservoir
bolts and the clutch cable holder
bolt, and then turn the coolant res-
ervoir upside-down to empty it.
6. Install the coolant reservoir and
the clutch cable holder by install-
ing the bolts.7. Remove the coolant drain bolt to
drain the cooling system.
