Checking the spark plug
The spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause
any spark plug to slowly erode, the
spark plug should be removed and
checked in accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
To remove the spark plug
1. Remove the spark plug cap.

2. Spark plug wrench

2. Remove the spark plug as
shown, with the spark plug
wrench included in the owner’s
tool kit.
To check the spark plug
1. Check that the porcelain insula-
tor around the center electrode of
the spark plug is a medium-to-
light tan (the ideal color when the
vehicle is ridden normally).
TIP
If the spark plug shows a distinctly
different color, the engine could be
operating improperly. Do not attempt
to diagnose such problems yourself.
Instead, have a Yamaha dealer check
the vehicle.
2. Check the spark plug for electro-
de erosion and excessive carbon
or other deposits, and replace it if
necessary.3. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to spe-
cification.
1. Spark plug gap
To install the spark plug
1. Clean the surface of the spark
plug gasket and its mating surfa-
ce, and then wipe off any grime
from the spark plug threads.
2. Install the spark plug with the
spark plug wrench, and then
tighten it to the specified torque.
TIP
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. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
3. Install the spark plug cap.
Tightening torque:
Spark plug:
12.5 Nm (1.25 m·kgf, 9.0 ft·lbf)
Spark plug gap:
0.7–0.8 mm (0.028–0.031 in)

Engine oil and oil filter
element
The engine oil level should be chec-
ked before each ride. In addition, the
oil must be changed and the oil filter
element replaced at the intervals spe-
cified in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
TIP
Make sure that the vehicle is positio-
ned 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
10–15 minutes, and then turn it
off.
3. Remove the oil filler cap, wipe the
dipstick clean, insert it back into
the oil filler hole (without scre-
wing it in), and then remove it
again to check the oil level.
TIP
The engine oil tank is located
inside of the frame.
The engine oil should be between
the minimum and maximum level
marks.
1. Engine oil filler cap
2. Maximum level mark
3. Minimum level mark
EWA10361
Never remove the engine oil tank
cap after high-speed operation,
otherwise hot engine oil could
spout out and cause damage or
injury. Always let the engine oil cool
down sufficiently before removing
the oil tank cap.
4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to rai-
se it to the correct level. NOTICE:
Do not operate the vehicle until
you know that the engine oil
level is sufficient.
[ECA10011]
5. Install the oil filler cap.
To change the engine oil (with or
without oil filter element
replacement)
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Remove the engine guard by
removing the screws.

ment drain bolt to their specified
torques.

13. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil
filler cap.
ECAM1061
The engine oil tank must be filled in
2 steps. First, fill the engine oil tank
with 1.90 L (2.0 US qt, 1.67 Imp.qt)
of the recommended engine oil.
Then, start the engine, race it 5 or 6
times, turn it off, and then add the
remainder of the engine oil.
TIP
Be sure to wipe off spilled oil on any
parts after the engine and exhaust
system have cooled down.
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 hig-
her quality than specified. In
addition, do not use oils labe-
led “ENERGY CONSERVING II”
or higher.
Make sure that no foreign
material enters the crankcase.
14. 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 cau-
se.
15. Turn the engine off, and then
check the oil level and correct it if
necessary.16. Install the engine guard by insta-
lling the screws.
NOTICE

Coolant
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU20253
To check the coolant level
1. Place the vehicle on a level surface
and hold it in an upright position.
TIP
The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
Make sure that the vehicle 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.
TIP
The coolant should be between the
minimum and maximum level marks.
1. Coolant reservoir
2. Maximum level mark
3. Minimum level mark
4. Coolant reservoir cap
3. If the coolant is at or below the
minimum level mark, remove
panel E (See page 6-8). , remove
the reservoir cap, add coolant to
the maximum level mark, and
then install the reservoir cap and
the panel. 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 avai-
lable, 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 coolant
as soon as possible, otherwise
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.
[ECA10472]
Coolant reservoir capacity (up to
the maximum level mark):

Changing the coolant
The coolant must be changed at the
intervals specified in the periodic
maintenance and lubrication chart.
Have a Yamaha dealer change the
coolant. WARNING! Never attempt
to remove the radiator cap when
the engine is hot.

Replacing the air filter
element and cleaning the
check hose
The air filter element should be repla-
ced at the intervals specified in the
periodic maintenance and lubrication
chart. Replace the air filter element
more frequently if you are riding in
unusually wet or dusty areas. In addi-
tion, the air filter check hose must be
frequently checked and cleaned if
necessary.
To replace the air filter element
1. Remove the seat. (See page
3-16).
2. Remove the air filter case cover
by removing the screws.
1. Air filter case cover
2. Screw
3. Pull the air filter element out.
4. Insert a new air filter element into
the air filter case as shown.
NOTICE: Make sure that the air
filter element is properly sea-
ted in the air filter case. The
engine should never be opera-
ted without the air filter ele-
ment installed, otherwise the
piston(s) and/or cylinder(s)
may become excessively worn.
