Periodic maintenance chartsTIP
Items marked with an asteri sk should be performed by your Yamaha dealer because these items require special tools,
data, and technical skills.

From 50000 km (30000 mi), repeat the maintenance intervals starting from 10000 km (6000 mi).

The annual checks must be performed every year, except if a distance-based maintenance is performed in-stead.

Checking the spark plugsThe 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.
NOTICE
ECA10841
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, twistit back and forth while pushing it in.

CanisterThis 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 oilThe 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 chart.NOTICE


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.

To check the engine oil level 1. After warming up the engine, wait a few minutes for the oil level to
settle for an accurate reading.
2. With the vehicle on a level surface, hold it upright for an accurate read-
ing.
3. Check the oil level through the check window located at the bot-
tom of the left-side of the crank-
case.
TIPThe engine oil should be between theminimum and maximum level marks. 4. If the engine oil is at or below the
minimum level mark, remove the
oil filler cap and add oil 5. Check the O-ring for damage, and
replace if necessary.
6. Install the engine oil filler cap.
To change the engine oil (and filter) 1. Start the engine, warm it up for several minutes, and then turn it
off.
2. Place an oil pan under the engine to collect the used oil.
3. Remove the engine oil filler cap, the engine oil drain bolt and its
gasket to drain the oil from the
crankcase.

the bolt to the specified torque.
8. Refill with the specified amount of the recommended engine oil.
TIPWipe off any spilled oil before startingthe engine.
9. Check the O-ring for damage, and then install the oil filler cap. 10. Start the engine and let it idle for
several minutes while checking for
oil leakage. If any leakage is
found, immediately stop the en-
gine and check for the cause.
TIPAfter the engine is started, the oil pres-
sure warning light should go off if the oillevel is sufficient.NOTICE
ECA20860
If the oil pressure warning light flick-
ers or remains on even if the oil level
is correct, immediately turn the en-
gine 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 one last time.

Why YamalubeYAMALUBE 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.

CoolantThe coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.TIPIf genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilledwater at a 1:1 ratio.
EAU20097
To 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. With the vehicle in an upright posi- tion, look at the coolant level in the reservoir.
3. If the coolant is at or below the minimum level mark, remove the
coolant reservoir cap. WARNING!
Remove only the coolant reser-
voir cap. Never attempt to re-
move the radiator cap when the
engine is hot.
[EWA15162]
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): 2.25 L (2.38 US qt, 1.98 Imp.qt)

4. 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]
5. Install the coolant reservoir cap.
EAU33032
Changing the coolant
The coolant must be changed at the in-
tervals specified in the periodic mainte-
nance and lubrication chart. Have a
Yamaha dealer change the coolant.
WARNING! Never attempt to remove
the radiator cap when the engine is
hot.
