Engine oil and oil filter
element
The engine oil level should be checked
before each ride. In addition, the oil must
be changed and the oil filter element re-
placed at the intervals specified in the
periodic maintenance and lubrication
chart.
To check the engine oil level
1. Place the vehicle on a level surface
and hold it in an upright position.
TIP
Make sure that the vehicle is posi-
tioned straight up when checking the
oil level. A slight tilt to the side can re-
sult 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 screwing
it in), and then remove it again to
check the oil level.

Tightening torque:
Spark plug:
12.5 Nm (1.25 m·kgf, 9.0 ft·lbf)
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
specified torque as soon as possible.
4. Install the spark plug cap.

ECAM1060CAUTION:
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.
NOTE:
Be sure to wipe off spilled oil on any
parts after the engine and exhaust
system have cooled down.
ECA11620CAUTION:  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
higher quality than specified. In
addition, do not use oils la-
beled “ENERGY CONSERVING
II” or higher.
 Make sure that no foreign ma-
terial 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 en-
gine off and check for the cause.
15. Turn the engine off, and then check the oil level and correct it if
necessary.
16. Install the engine guard by in- stalling the screws.

Coolant
The coolant level should be checked
before each ride. In addition, the
coolant must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart.
EAU20253
To check the coolant level1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.
NOTE:
The 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.

Cleaning and lubricating
the drive chain
The drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly
wear out, especially when riding in
dusty or wet areas. Service the drive
chain as follows.
ECA10581
NOTICE
The drive chain must be lubricated
after washing the motorcycle and
riding in the rain.
1. Clean the drive chain with kerosene
and a small soft brush. NOTICE:
To prevent damaging the O-
rings, do not clean the drive
chain with steam cleaners,
high-pressure washers or inap-
propriate solvents.2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant. NOTICE:Do not use
engine oil or any other lubri-
cants for the drive chain, as
they may contain substances
that could damage the O-rings.
EAU23101
Checking and lubricating
the cables
The operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubri-
cated if necessary. If a cable is dam-
aged or does not move smoothly, have
a Yamaha dealer check or replace it.
WARNING! Damage to the outer
sheath may interfere with proper
cable operation and will cause the
inner cable to rust. Replace a dam-
aged cable as soon as possible to
prevent unsafe conditions.

Care
While the open design of a motorcycle
reveals the attractiveness of the tech-
nology, it also makes it more vulnera-
ble. Rust and corrosion can develop
even if high-quality components are
used. A rusty exhaust pipe may go un-
noticed on a car, however, it detracts
from the overall appearance of a mo-
torcycle. Frequent and proper care
does not only comply with the terms of
the warranty, but it will also keep your
motorcycle looking good, extend its
life and optimize its performance.
Before cleaning
1. Cover the muffler outlet with a
plastic bag after the engine has
cooled down.
2. Make sure that all caps and cov-
ers as well as all electrical cou-
plers and connectors, including
the spark plug cap, are tightly in-
stalled.3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such prod-
ucts onto seals, gaskets, sprockets,
the drive chain and wheel axles. Al-
ways rinse the dirt and degreaser
off with water.
Cleaning
ECA10772
NOTICE
●Avoid using strong acidic
wheel cleaners, especially on
spoked wheels. If such prod-
ucts are used on hard-to-re-
move dirt, do not leave the
cleaner on the affected area
any longer than instructed. Al-
so, thoroughly rinse the area
off with water, immediately dry
it, and then apply a corrosion
protection spray.
●Improper cleaning can damage
plastic parts (such as cowlings,
panels, windshields, headlight
lenses, meter lenses, etc.) and
the mufflers. Use only a soft,
clean cloth or sponge with wa-ter to clean plastic. However, if
the plastic parts cannot be
thoroughly cleaned with water,
diluted mild detergent with wa-
ter may be used. Be sure to
rinse off any detergent residue
using plenty of water, as it is
harmful to plastic parts.
●Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive
cleaning products, solvent or
thinner, fuel (gasoline), rust re-
movers or inhibitors, brake flu-
id, antifreeze or electrolyte.
●Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the fol-
lowing areas: seals (of wheel
and swingarm bearings, fork
and brakes), electric compo-
nents (couplers, connectors,
instruments, switches and
lights), breather hoses and
vents.

●For motorcycles equipped with
a windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or
scratching. Some cleaning
compounds for plastic may
leave scratches on the wind-
shield. Test the product on a
small hidden part of the wind-
shield to make sure that it does
not leave any marks. If the
windshield is scratched, use a
quality plastic polishing com-
pound after washing.After normal use
Remove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottlebrush
for hard-to-reach areas. Stubborn dirt
and insects will come off more easily if
the area is covered with a wet cloth for
a few minutes before cleaning.
After riding in the rain, near the sea
or on salt-sprayed roads
Since sea salt or salt sprayed on roads
during winter are extremely corrosive
in combination with water, carry out
the following steps after each ride in
the rain, near the sea or on salt-
sprayed roads.
TIP
Salt sprayed on roads in the winter
may remain well into spring.
1. Clean the motorcycle with cold
water and a mild detergent, after
the engine has cooled down.NO-
TICE: Do not use warm water
since it increases the corrosive
action of the salt.2. Apply a corrosion protection
spray on all metal, including
chrome- and nickel-plated, sur-
faces to prevent corrosion.
After cleaning
1. Dry the motorcycle with a
chamois or an absorbing cloth.
2. Immediately dry the drive chain
and lubricate it to prevent it from
rusting.
3. Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally in-
duced discoloring of stainless-
steel exhaust systems can be re-
moved through polishing.)
4. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal, includ-
ing chrome- and nickel-plated,
surfaces.
5. Use spray oil as a universal clean-
er to remove any remaining dirt.
6. Touch up minor paint damage
caused by stones, etc.
7. Wax all painted surfaces.

Long-term
Before storing your motorcycle for sev-
eral months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
3. Perform the following steps to
protect the cylinder, piston rings,
etc. from corrosion.
a. Remove the spark plug cap
and spark plug.
b. Pour a teaspoonful of engine
oil into the spark plug bore.
c. Install the spark plug cap onto
the spark plug, and then place
the spark plug on the cylinder
head so that the electrodes
are grounded. (This will limit
sparking during the next step.)
d. Turn the engine over several
times with the starter. (This will
coat the cylinder wall with oil.)
e. Remove the spark plug cap
from the spark plug, and then
install the spark plug and the
spark plug cap. WARNING! Toprevent damage or injury
from sparking, make sure to
ground the spark plug elec-
trodes while turning the en-
gine over.
4. Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the side-
stand/centerstand.
5. Check and, if necessary, correct
the tire air pressure, and then lift
the motorcycle so that both of its
wheels are off the ground. Alter-
natively, turn the wheels a little
every month in order to prevent
the tires from becoming degraded
in one spot.
6. Cover the muffler outlets with
plastic bags to prevent moisture
from entering them.7. Remove the battery and fully
charge it. Store it in a cool, dry
place and charge it once a month.
Do not store the battery in an ex-
cessively cold or warm place [less
than 0 °C (30 °F) or more than 30
°C (90 °F)]. For more information
on storing the battery, see
page 7-31.
TIP
Make any necessary repairs before
storing the motorcycle.
