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.
1. Screw
2. Engine guard

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):
0.50 L (0.53 US qt, 0.44 Imp.qt)
