Checking the spark plugs
The spark plugs are important engine
components, which are easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plugs 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.
To remove a spark plug
1. Remove cowling B. (See
page 6-6.)
2. Remove the spark plug cover by
pulling it out as shown.3. Remove the spark plug cap.
4. Remove the spark plug as shown
with the spark plug wrench includ-
ed in the owner’s tool kit.

9 To check the spark plugs
1. Check that the porcelain insulator
around the center electrode on
each spark plug is a medi-
um-to-light tan (the ideal color
when the vehicle is ridden normal-
ly).
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 oper-
ating improperly. Do not attempt to
diagnose such problems yourself. In-
stead, have a Yamaha dealer check
the vehicle.
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 surface, 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.
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.
5. Place the spark plug cover in the
original position as shown, and
then install the cowling.

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 vehicle on the center-
stand.
CAUTION:

ECA11290
The engine must be cold before pro-
ceeding with the oil level check, oth-
erwise the check will result in a false
reading.
NOTE:

Make sure that the vehicle is positioned
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 two
minutes, and then turn it off.
3. Wait two minutes until the oil set-tles, and then check the oil level
through the check window located
at the bottom-left side of the crank-
case.
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 replace-
ment)
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the engine
to collect the used oil.
3. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.

NOTE:

not being replaced.
4. Remove the oil filter cartridge with
an oil filter wrench.
NOTE:

An oil filter wrench is available at a
Yamaha dealer.
5. Apply a thin coat of engine oil to
the O-ring of the new oil filter car-
tridge.
NOTE:

Make sure that the O-ring is properly
seated.
6. Install the new oil filter cartridge,
and then tighten it to the specified
torque with a torque wrench.7. Install the engine oil drain bolt, and
then tighten it to the specified
torque.
8. Add the specified amount of the
recommended engine oil, and then
install and tighten the oil filler cap.

CAUTION:

ECA11620

In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. 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, im-
mediately turn the engine off and
check for the cause.
10. Turn the engine off, and thencheck the oil level and correct it if
necessary.
11. Reset the oil change indicator ac-
cording to the following procedure.
To reset the oil change indicator
1. Turn the key to “ON”.
2. Hold the “OIL CHANGE” button
pushed for two to eight seconds.
3. Release the “OIL CHANGE” but-
ton, and the oil change indicator
will go off.
NOTE:

If the engine oil is changed before the
oil change indicator comes on (i.e. be-
fore the periodic oil change interval has
been reached), the indicator must bereset after the oil change for the next
periodic oil change to be indicated at
the correct time. To reset the oil change
indicator before the periodic oil change
interval has been reached, follow the
above procedure, but note that the indi-
cator will come on for 1.4 seconds after
releasing the “OIL CHANGE” button,
otherwise repeat the procedure.
Recommended engine oil:
See page 8-1.
Oil quantity:
Without oil filter cartridge replace-
ment:

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.
EAU42831
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
NOTE:


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

Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level through
the check window.
NOTE:

The coolant should be between the
minimum and maximum level marks.3. If the coolant is at or below the
minimum level mark, lift up the
right floorboard mat as shown.
4. Remove the coolant reservoir cov-

er by removing the screw.
5. Open the reservoir cap, add cool-
ant to the maximum level mark,
and then close the reservoir cap.
CAUTION:

ECA10471

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.

If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the cooling system will not
be protected against frost and
corrosion.

If water has been added to thecoolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.
WARNING

EWA10380
Never attempt to remove the radiator
cap when the engine is hot.
6. Install the coolant reservoir cover
by installing the screw.
7. Place the right floorboard mat in
the original position.
NOTE:


The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.

If the engine overheats, see page
6-36 for further instructions.
