6To install the cowling
1. Connect the turn signal light lead
connectors.
2. Place the cowling in the original
position.
3. Install the screw, tighten the quick
fastener screws, and then install
the quick fastener.NOTE:@ To install the quick fastener, push the
center pin out so that it will protrude
from the fastener head, insert the fas-
tener into the cowling, and then push
the protruding pin in until it is flush with
the fastener head. @4. Install the cowling and the panel.
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.

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.To change the engine oil
(with or without oil filter cartridge
replacement)
1. Remove cowling A. (See page 6-5

tion procedures.)1. Engine oil level check window

removing the bolt.
3. Start the engine, warm it up for
several minutes, and then turn it
off.
4. Place an oil pan under the engine
to collect the used oil.
5. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.
NOTE:@ Skip steps 6–8 if the oil filter cartridge is
not being replaced. @
6. Remove the oil filter cartridge with
an oil filter wrench.NOTE:@ An oil filter wrench is available at a
Yamaha dealer. @
7. Apply a thin coat of engine oil to
the O-ring of the new oil filter
cartridge.NOTE:@ Make sure that the O-ring is properly
seated. @

68. Install the new oil filter cartridge,
and then tighten it to the specified
torque with a torque wrench.
9. Install the engine oil drain bolt, and
then tighten it to the specified
torque.10. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil filler
cap.
EC000072
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.

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.
@
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
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
radiator.
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.
l
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.
