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.
Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads. Specified spark plug:
DPR8EA-9 (NGK) or
X24EPR-U9 (DENSO)

Engine oil and oil filter
element The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation 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
15 minutes, and then turn it off.3. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in and with the arrow
mark pointing upward as shown),
and then remove it again to check
the oil level.
NOTE:_ The engine oil should be between the
minimum and maximum level marks. _
EC000000
CAUTION:_ Do not operate the motorcycle until
you know that the engine oil level is
sufficient. _
EW000065
WARNING
_ Never remove the engine oil tank
cap after high-speed operation, oth-
erwise hot engine oil could spout
out and cause damage or injury. Al-
ways let the engine oil cool down
sufficiently before removing the oil
tank cap. _

65. Remove and replace the oil filter
element and O-rings.
6. Install the oil filter element cover
by installing the bolts, then tighten-
ing them to the specified torque.
NOTE:_ Make sure that the O-rings are properly
seated. _7. Install the engine oil drain bolts,
and then tighten them to the spec-
ified torques.8. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil filler
cap.
EC000072
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.
10. Turn the engine off, and then
check the oil level and correct it if
necessary.

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
minimum level mark, remove
panel B (See page 6-6 for panel
removal and installation proce-
dures.), remove the reservoir cap,
add coolant to the maximum level
mark, and then install the reservoir
cap and the panel.

CAUTION:_
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 engine may not be
sufficiently cooled and the cool-
ing system will not be protected
against frost and corrosion.
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.

WARNING
_ Never attempt to remove the radia-
tor cap when the engine is hot. _
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
6-44 for further instructions.

EAU04461
To change the coolant
1. Place the motorcycle on a level
surface and let the engine cool if
necessary.
2. Remove the seat. (See page 3-11
for seat removal and installation
procedures.)
3. Remove cowling B and panel B.
(See pages 6-5 and 6-6 for cowl-
ing and panel removal and instal-
lation procedures.)
4. Remove the fuel tank bolts, and
then lift the fuel tank to position it
away from the coolant reservoir.
(Do not disconnect the fuel hos-
es!)
5. Place a container under the en-
gine to collect the used coolant.

then tighten them to the specified
torque.
NOTE:_ Check the washers for damage and re-
place them if necessary. _14. Pour the recommended coolant
into the radiator until it is full.

_15. Install the radiator cap, start the
engine, let it idle for several min-
utes, and then turn it off.

the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap and the cap retaining bolt.

ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.
