Do not touch the glass part of the head-
light bulb to keep it free from oil, other-
wise the transparency of the glass, the
luminosity of the bulb, and the bulb life
will be adversely affected.
Thoroughly clean off any dirt and fin-
gerprints on the headlight bulb using a
cloth moistened with alcohol or thin-
ner.
CAUTION:5. Install the headlight bulb cover, and
then connect the coupler and auxil-
iary light leads.
6. Remove the socket (together with the
bulb) by turning it counterclockwise.
7. Remove the defective bulb by push-
ing it in and turning it counterclock-
wise.
8. Insert a new bulb into the socket,
push it in, and then turn it clockwise
until it stops.
9. Install the socket (together with the
bulb) by turning it clockwise.10. Connect the auxiliary light bulb leads.
11. Tilt the cowling back to the original
position, and then install the headlight
by installing the screws.

MOTORCYCLE CARE AND STORAGE
Care
While the open design of a motorcycle re-
veals 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 unnoticed 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 motor-
cycle looking good, extend its life and opti-
mize its performance.Before cleaning
1. Cover the muffler outlets with plastic
bags after the engine has cooled
down.
2. Make sure that all caps and covers as
well as all electrical couplers and con-
nectors, including the spark plug
caps, are tightly installed.
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 and wheel axles. Al-
ways rinse the dirt and degreaser off
with water.CleaningECA00010
•Avoid using strong acidic wheel
cleaners, especially on spoked
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, thoroughly rinse the area off
with water, immediately dry it, and
then apply a corrosion protection
spray.
•Improper cleaning can damage
windshields, cowlings, panels and
other plastic parts. Use only a soft,
clean cloth or sponge with mild
detergent and water to clean plas-
tic.

MOTORCYCLE CARE AND STORAGE
After cleaning
1. Dry the motorcycle with a chamois or
an absorbing cloth.
2. Use a chrome polish to shine chrome,
aluminum and stainless-steel parts,
including the exhaust system. (Even
the thermally induced discoloring of
stainless-steel exhaust systems can
be removed through polishing).
3. To prevent corrosion, it is recom-
mended to apply a corrosion protec-
tion spray on all metal, including
chrome- and nickel-plated, surfaces.
4. Use spray oil as a universal cleaner
to remove any remaining dirt.
5. Touch up minor paint damage caused
by stones, etc.
6. Wax all painted surfaces.
7. Let the motorcycle dry completely be-
fore storing or covering it.EWA00031WARNING0
•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 cor-
nering behavior.
ECA00013
•Apply spray oil and wax sparingly
and make sure to wipe off any
excess.
•Never apply oil or wax to any rub-
ber and plastic parts, but treat
them with a suitable care product.
•Avoid using abrasive polishing
compounds as they will wear away
the paint.
NOTE:
Consult a Yamaha dealer for advice on
what products to use.

MOTORCYCLE CARE AND STORAGE
Storage
Short-term
Always store your motorcycle in a cool, dry
place and, if necessary, protect it against
dust with a porous cover.
ECA00014
•Storing the motorcycle in a poorly
ventilated 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 ammonia) and areas
where strong chemicals are
stored.
CAUTION:Long-term
Before storing your motorcycle for several
months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. For motorcycles equipped with a fuel
cock that has an “OFF” position: Turn
the fuel cock lever to “OFF”.
3. Drain the carburetor float chambers
by loosening the drain bolts; this will
prevent fuel deposits from building
up. Pour the drained fuel into the fuel
tank.
4. Fill up the fuel tank and add fuel sta-
bilizer (if available) to prevent the fuel
tank from rusting and the fuel from
deteriorating.
5. Perform the following steps to protect
the cylinders, piston rings, etc. from
corrosion.a. Remove the spark plug caps and
spark plugs.
b. Pour a teaspoonful of engine oil into
each spark plug bore.
c. Install the spark plug caps onto the
spark plugs, and then place the spark
plugs 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 walls with oil).
e. Remove the spark plug caps from the
spark plugs, and then install the spark
plugs and the spark plug caps.
EWA00003WARNING0
To prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turning the
engine over.

Be sure to use motor oils that do not contain anti-friction modifiers.
Passenger car motor oils (often labeled “ENERGY CONSERVING II”)
contain anti-friction additives which will cause clutch and/ or starter
clutch slippage, resulting in reduced component life and poor
engine performance.8
