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 color
when the vehicle is ridden normally),
and all spark plugs installed in the en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
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 replaced if
out of specification.
Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.

TIPIf 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.NOTICE
ECA10840
Do not use any tools to remove or in-
stall the spark plug cap, otherwise
the ignition coil coupler may get
damaged. The spark plug cap may
be difficult to remove because the
rubber seal on the end of the cap fits
tightly. To remove the spark plug
cap, simply twist it back and forth
while pulling it out; to install it, twist
it back and forth while pushing it in.
EAU19908
Engine oil and oil filter car-
tridge 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 level1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion. 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.TIPThe 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. Place the vehicle on a level sur- face.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Place an oil pan under the engine to collect the used oil.

4. Remove the engine oil filler cap,
the engine oil drain bolt and its
gasket to drain the oil from the
crankcase.
TIPSkip steps 5–7 if the oil filter cartridge is
not being replaced.5. Remove the oil filter cartridge withan oil filter wrench.TIPAn oil filter wrench is available at a
Yamaha dealer.6. Apply a thin coat of clean engineoil to the O-ring of the new oil filter
cartridge.
TIPMake sure that the O-ring is properly
seated.7. Install the new oil filter cartridgewith an oil filter wrench, and then
tighten it to the specified torque
with a torque wrench.

9. Refill with the specified amount of the recommended engine oil, and
then install and tighten the oil filler
cap.

●
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.
10. 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.TIPAfter the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient.NOTICE
ECA10401
If the oil level warning light flickers
or remains on even if the oil level is
correct, immediately turn the engine
off and have a Yamaha dealer check
the vehicle.11. Turn the engine off, wait a few min-utes until the oil settles, 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.
EAU46691
To check the coolant level1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.TIP●
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 in the cool-ant reservoir.TIPThe coolant should be between the
minimum and maximum level marks.

63. If the coolant is at or below the
minimum level mark, remove the
coolant reservoir cap guard by re-
moving the bolt, and then remove
the reservoir cap.
4. Add coolant to the maximum level mark, and then install the reservoir
cap. WARNING! Remove only
the coolant reservoir cap. Never
attempt to remove the radiator
cap when the engine is hot.
[EWA15161]
NOTICE: 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 the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possible, otherwise the
effectiveness of the coolant will
be reduced.

5. Install the coolant reservoir cap
guard by installing the bolt.

To change the coolant1. Place the vehicle on a level sur- face and let the engine cool if nec-
essary.
2. Remove cowling A. (See page 6-8.) 3. Remove the air intake duct by re-
moving the bolts.
