MOTORCYCLE CARE AND STOR-
AGE
EAS2GC1059CARE
While the open design of a motorcycle reveals
the attractiveness of the technology, it also
makes it more vulnerable. Rust and corrosion
can develop even if high-quality components
are used. A rusty exhaust pipe may go unno-
ticed on a car, however, it detracts from the
overall appearance of a motorcycle. 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 op-
timize its performance.
Before cleaning
1. Cover the muffler outlet with a plastic bag af-ter the engine has cooled down.
2. Make sure that all caps and covers as well as all electrical coup lers and connectors, in-
cluding 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
products onto seals, gaskets, sprockets, the
drive chain and wheel axles. Always rinse
the dirt and degreaser off with water.
Cleaning
ECA
NOTICE
• Avoid using strong acidic wheel cleaners, especially on spoked wheels. If such prod-
ucts are used on hard-to-remove dirt, do
not leave the cleaner on the affected area
any longer than instructed. Also, thor-
oughly rinse the area off with water, imme-
diately dry it, and then apply a corrosion
protection spray.
• Improper cleaning can damage plastic parts (such as cowlings, panels, wind-
shields, headlight lenses, meter lenses,
etc.) and the mufflers. Use only a soft,
clean cloth or sponge with water to clean
plastic. However, if the plastic parts can-
not be thoroughly cleaned with water, di-
luted 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 con-
tact with strong or abrasive cleaning prod-
ucts, solvent or thinner, fuel (gasoline),
rust removers or inhibitors, brake fluid,
antifreeze or electrolyte.
• Do not use high-pressure washers or steam-jet cleaners since they cause water
seepage and deterioration in the following
areas: seals (of wheel and swingarm bear-
ings, fork and brakes), electric compo-
nents (couplers, connectors, instruments,
switches and lights), breather hoses and
vents.
• For motorcycles equipped with a wind-
shield: 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 windshield to make sure that it
does not leave any marks. If the wind-
shield 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 thor-
oughly 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 min-
utes 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.
NOTICE: 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,
surfaces to prevent corrosion.
After cleaning
1. Dry the motorcycle with a chamois or an ab- sorbing cloth.
2. Immediately dry the drive chain and lubri- cate it to prevent it from rusting.
3. Use a chrome polish to shine chrome, alumi-
num and stainless- st eel parts, including the
exhaust system. (Even the thermally in-
duced discoloring of stainless- steel exhaust
systems can be removed through polishing.)
4. To prevent corrosion, it is recommended to apply a corrosion protection spray on all
metal, including chrome- and nickel-plated,
surfaces.
5. Use spray oil as a universal cleaner to re- move any remaining dirt.
6. Touch up minor paint damage caused by stones, etc.
7. Wax all painted surfaces.
8. Let the motorcycle dry completely before
storing or covering it.
EWA
WARNING
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 higher speeds, test the motorcy-
cle’s braking performance and cornering
behavior.
ECA
NOTICE
• Apply spray oil and wax sparingly 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 com-
pounds 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.
EAS2GC1060STORAGE
Short-term
Always store your motorcycle in a cool, dry
place and, if necessary, protect it against dust
with a porous cover. Be sure the engine and the
exhaust system are cool before covering the
motorcycle.
ECA
NOTICE
• Storing the motorcycle in a poorly ventilat-ed room or covering it with a tarp, while it
is still wet, will allow water and humidity to
seep in and cause rust.
• To prevent corrosion, avoid damp cellars,
stables (because of the presence of am-
monia) and areas where strong chemicals
are stored.
Long-term
Before storing your motorcycle for several
months:
1. Follow all the instructions in the “Care” sec- tion of this chapter.
2. Fill up the fuel tank and add fuel stabilizer (if
available) to prevent the fuel tank from rust-
ing 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.)
