Engine overheatingEWA10400
●Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
●After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the his-
sing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
TIP
If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended
coolant as soon as possible.
Wait until the
engine has cooled.Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.
The coolant level is low.
Check the cooling system
for leakage.

Matte color cautionECA15192
Some models are equipped with
matte colored finished parts. Be
sure to consult a Yamaha dealer for
advice on what products to use
before cleaning the vehicle.
Using a brush, harsh chemical pro-
ducts or cleaning compounds
when cleaning these parts will
scratch or damage their surface.
Wax also should not be applied to
any matte colored finished parts.
EAU26004
Care
While the open design of a motorcy-
cle reveals the attractiveness of the
technology, it also makes it more vul-
nerable. Rust and corrosion can
develop even if high-quality compo-
nents are used. A rusty exhaust pipe
may go unnoticed on a car, however,
it detracts from the overall appearan-
ce of a motorcycle. Frequent and pro-
per 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
covers as well as all electrical
couplers and connectors, inclu-
ding the spark plug cap, are
tightly installed.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and abrush, but never apply such pro-
ducts onto seals, gaskets, sproc-
kets, the drive chain and wheel
axles. Always rinse the dirt and
degreaser off with water.
Cleaning
ECA10772
●Avoid using strong acidic whe-
el cleaners, especially on spo-
ked wheels. If such products
are used on hard-to-remove
dirt, do not leave the cleaner on
the affected area any longer
than instructed. Also, tho-
roughly rinse the area off with
water, immediately dry it, and
then apply a corrosion protec-
tion 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
water to clean plastic. Howe-
ver, if the plastic parts cannot
be thoroughly cleaned with

water, diluted mild detergent
with water 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
removers or inhibitors, brake
fluid, antifreeze or electrolyte.
●Do not use high-pressure was-
hers or steam-jet cleaners sin-
ce they cause water seepage
and deterioration in the follo-
wing areas: seals (of wheel and
swingarm bearings, fork and
brakes), electric components
(couplers, connectors, instru-
ments, 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 scrat-
ching. Some cleaning com-pounds for plastic may leave
scratches on the windshield.
Test the product on a small hid-
den part of the windshield to
make sure that it does not lea-
ve any marks. If the windshield
is scratched, use a quality
plastic polishing compound
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 bottle-
brush for hard-to-reach areas. Stub-
born 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 aftereach 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.
NOTICE: Do not use warm
water since it increases the
corrosive action of the salt.
[ECA10791]
2. Apply a corrosion protection
spray on all metal, including
chrome- and nickel-plated, surfa-
ces to prevent corrosion.
After cleaning
1. Dry the motorcycle with a cha-
mois 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 indu-
ced discoloring of stainless-steel

exhaust systems can be removed
through polishing.)
4. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal, inclu-
ding chrome- and nickel-plated,
surfaces.
5. Use spray oil as a universal clea-
ner to remove any remaining dirt.
6. Touch up minor paint damage
caused by stones, etc.
7. Wax all painted surfaces.
8. Let the motorcycle dry comple-
tely before storing or covering it.
EWA11131
Contaminants on the brakes or
tires can cause loss of control.
●Make sure that there is no oil or
wax on the brakes or tires.
●If necessary, clean the brake
discs and brake linings with a
regular brake disc cleaner or
acetone, and wash the tires
with warm water and a mild
detergent. Before riding at hig-
her speeds, test the motorcy-cle’s braking performance and
cornering behavior.
ECA10800
●Apply spray oil and wax spa-
ringly and make sure to wipe
off any excess.
●Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.
●Avoid using abrasive polishing
compounds as they will wear
away the paint.
TIP
●Consult a Yamaha dealer for
advice on what products to use.
●Washing, rainy weather or humid
climates can cause the headlight
lens to fog. Turning the headlight
on for a short period of time will
help remove the moisture from
the lens.
EAU37221
Storage
Short-term
Always store your motorcycle in a
cool, dry place and, if necessary, pro-
tect it against dust with a porous
cover.
ECA10810
●Storing the motorcycle in a
poorly ventilated room or cove-
ring it with a tarp, while it is still
wet, will allow water and humi-
dity to seep in and cause rust.
●To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.
Long-term
Before storing your motorcycle for
several months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Turn the fuel cock lever to “OFF”.
3. Drain the carburetor float cham-
ber by loosening the drain bolt;
this will prevent fuel deposits

from building up. Pour the drai-
ned fuel into the fuel tank.
4. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
5. 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!
To prevent damage or injuryfrom sparking, make sure
to ground the spark plug
electrodes while turning the
engine over.
[EWA10951]
6. Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
7. 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 degra-
ded in one spot.
8. Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.
9. 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 excessively cold or warm pla-
ce [less than 0 °C (30 °F) or more
than 30 °C (90 °F)]. For more
information on storing the bat-
tery, see page 6-30.
TIP
Make any necessary repairs before
storing the motorcycle.
