TIP Air filter
• This model’s air filter is equipped with a disposable oil-coated paper element, which must not be cleaned with com- pressed air to avoid damaging it.
• The air filter element needs to be replaced more frequently when riding in unusually wet or dusty areas.
Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level.
• Every two years replace the internal components of the brake master cylinders and calipers, and change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.

Checkin g the spark plu gsThe spark plugs are important engine
components, which should be
checked periodically, preferably by a
Yamaha dealer. Since heat and depos- its will cause any spark plug to slowly
erode, they should be removed and
checked in accordance with the peri-
odic maintenance and lubrication
chart. In addition, the condition of the
spark plugs can reveal the condition of
the engine.
The porcelain insulator around the
center 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 engine should have the same
color. If any spark plug shows a dis-
tinctly different color, the engine could
be operating improperly. Do not at-
tempt to diagnose such problems
yourself. Instead, have a Yamaha deal-
er check the vehicle.
If a spark plug shows signs of elec-
trode 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.
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
specified torque as soon as possible.NOTICE
ECA10841
Do not use any tools to remove or in-
stall the spark plu
g cap, otherwise
the i gnition coil coupler may get
d amag ed . The spark plu g cap may
b e difficult to remove b ecause the
ru bber seal on the en d of the cap fits
ti g htly. To remove the spark plu g
cap, simply twist it b ack and forth
while pullin g it out; to install it, twist
it back an d forth while pushin g it in.

En gine oil an d oil filter car-
tri dgeThe 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 en gine oil level
1. Place the vehicle on a level surfa- ce 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 engine oil level check
window located at the bottom-left
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 chan ge the en gine oil (with or
without oil filter cartri dge replace-
ment) 1. Place the vehicle on a level surfa- ce.
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.

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. 8. Install the engine oil drain bolt and

In or der to prevent clutch slip-
pa ge (since the en gine oil also
lu bricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a hi gh-
er quality than specifie d. In
a ddition, do not use oils lab eled
“ENERGY CONSERVING II” or
hi gher.
Make sure that no forei gn 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,
immediately turn the engine off
and check for the cause.TIPAfter the engine is started, the engine
oil pressure warning light should go off.NOTICE
ECA20860
If the oil pressure warnin g li ght flick-
ers or remains on even if the oil level
is correct, imme diately turn the en-
g ine off an d have a Yamaha dealer
check the vehicle.11. Turn the engine off, wait a few mi- nutes until the oil settles, and then
check the oil level and correct it if
necessary.

CoolantThe 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.
EAU20095
To check the coolant level1. Place the vehicle on a level surfa- ce and hold it in an upright posi-
tion.TIPThe coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
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
coolant reservoir.TIPThe coolant should be between the mi-
nimum and maximum level marks.

3. If the coolant is at or below the mi-
nimum level mark, remove the res-
ervoir cap. WARNING! Remove
only the coolant reservoir cap.
Never attempt to remove the ra-
d iator cap when the en gine is

4. Add coolant to the maximum level mark, and then install the reservoir
cap. NOTICE: If coolant is not
availa ble, use d istilled water or
soft tap water instead . Do not
use har d water or salt water
since it is harmful to the en gine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not
b e protecte d a gainst frost an d
corrosion. If water has been
a dde d to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as soon as possi
ble, otherwise the
effectiveness of the coolant will
b e re duce d.
