Emission controls not only function to
ensure cleaner air, but are also vital to
proper engine operation and maximum
performance. In the following periodic
maintenance charts, the services relat-
ed to emissions control are grouped
separately. These services require
specialized data, knowledge, and
equipment. Maintenance, replacement,
or repair of the emission control devic-
es and systems may be performed by
any repair establishment or individual
that is certified (if applicable). Yamaha
dealers are trained and equipped to
perform these particular services.

Air filters
The engine air filter uses a disposable oil-coated paper element. This element
cannot be cleaned with compressed air, doing so will only damage it.
If you often ride in the rain or in dusty areas, have the engine air filter and V-
belt air filter elements serviced more frequently.
Hydraulic brake service
Regularly check the brake fluid levels in the reservoirs, and refill as necessary.
Replace the internal components of the brake master cylinders and calipers,
and change the brake fluid every 2 years.
Replace the brake hoses every 4 years, or sooner if cracked or damaged.

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, 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.
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. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible.
Specified spark plug:
NGK/CR7E
1. Spark plug gap
Spark plug gap:0.7–0.8 mm (0.028–0.031 in)
Tightening torque: Spark plug:

Canister
This model is equipped with a canister
to prevent the discharging of fuel vapor
into the atmosphere. Before operating
this vehicle, make sure to check the fol-
lowing:
Check each hose connection.
Check each hose and canister for
cracks or damage. Replace if dam-
aged.
Make sure that the canister breath-
er is not blocked, and if necessary,
clean it.

Engine oil and oil filter
cartridge
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 level 1. Place the vehicle on the center- stand. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for two minutes, and then turn it off.
3. Wait two minutes until the oil level settles.
4. Check the oil level through the check window located at the bot-
tom-left side of the crankcase.
TIP
The engine oil should be between the
minimum and maximum level marks.
5. 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.

NOTICE
ECA11621
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.
12. 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.
13. Turn the engine off, and then check the oil level and correct it if
necessary.
14. Reset the oil change indicator. (See page 5-10.)

Why Yamalube
YAMALUBE oil is a Genuine YAMAHA
Part born of the engineers’ passion and
belief that engine oil is an important liq-
uid engine component. We form teams
of specialists in the fields of mechanical
engineering, chemistry, electronics and
track testing, and have them develop
the engine together with the oil it will
use. Yamalube oils take full advantage
of the base oil’s qualities and blend in
the ideal balance of additives to make
sure the final oil clears our performance
standards. Thus, Yamalube mineral,
semisynthetic and synthetic oils have
their own distinct characters and value.
Yamaha’s experience gained over
many years of research and develop-
ment into oil since the 1960’s helps
make Yamalube the best choice for
your Yamaha engine.
EAUS1203
Coolant
The coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.
TIP
If genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilled
water at a 1:1 ratio.
EAU52025To check the coolant level
Since the coolant level varies with en-
gine temperature, check when the en-
gine is cold. 1. Park the vehicle on a level surface.
2. Hold the vehicle upright, or place it on the centerstand.
3. Look at the coolant level through the check window.
Recommended coolant:YAMALUBE coolant
Coolant quantity: Coolant reservoir (max level mark):0.25 L (0.26 US qt, 0.22 Imp.qt)
Radiator (including all routes): 1.67 L (1.77 US qt, 1.47 Imp.qt)

4. If the coolant is at or below the
minimum level mark, remove the
left floorboard mat by pulling it up.
5. Remove the coolant reservoir cov- er by removing the screws.
6. Remove the coolant reservoir cap. WARNING! Remove only the coolant reservoir cap. Never at-
tempt to remove the radiator
cap when the engine is
hot.
[EWA15162]
7. Add coolant to the maximum level
mark. 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.
[ECA10473]
8. Install the coolant reservoir cap.
9. Install the coolant reservoir cover.
10. Install the floorboard mat.
EAU33032Changing the coolant
The coolant must be changed at the in-
