EAU01301A. CLEANING
Frequent, thorough cleaning of
your motorcycle will not only
enhance its appearance but will
improve its
general performance and extend
the useful life of many compo-
nents.

8Improper cleaning can damage
the cowlings, panels and other
plastic parts. Use only a soft,
clean cloth or sponge with
mild detergent and water to
clean plastic.
8Do 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 abra-
sive cleaning products, solvent
or thinner, fuel (gasoline), rust
removers or inhibitors, brake
fluid, antifreeze or electrolyte.
EC000111
cC
Excessive hose pressure may
cause water seepage and deterio-
ration of wheel bearings, front
fork, brakes, transmission seals
and electrical parts.
Many expensive repair bills have
resulted from improper high pres-
sure detergent applications such
as those available in coin-operated
car washers.
4. After riding on salted roads,
wash the motorcycle with cold
water immediately. Do not use
warm water as it increases the
chemical reaction of the salt.
5. Once the majority of the dirt
has been hosed off, wash all
surfaces with warm water and
mild, detergent-type soap. An
old toothbrush or bottle brush
is handy for hard-to-get-at
places. 1. Before cleaning the motorcy-
cle:
a. Block off the end of the
exhaust pipe to prevent water
entry; a plastic bag and strong
rubber band may be used.
b. Make sure the spark plug and
all filler caps are properly
installed.
2. If the engine case is excessive-
ly greasy, apply degreaser
with a paint brush. Do not
apply degreaser to the chain,
sprockets or wheel axles.
3. Rinse the dirt and degreaser
off with a garden hose. Use
only enough pressure to do
the job.

96. Rinse the motorcycle off
immediately with clean water
and dry all surfaces with a
chamois, clean towel, or soft
absorbent cloth.
7. Dry the chain and lubricate it
to prevent rust.
8. Clean the seat with a vinyl
upholstery cleaner to keep the
cover pliable and glossy.
9. Automotive-type wax may be
applied to all painted and
chrome-plated surfaces. Avoid
combination cleaner-waxes.
Many contain abrasives which
may mar the paint or protec-
tive finish. When finished, start
the engine and let it idle for
several minutes.
EAU01107B. STORAGE
Long term storage (60 days or
more) of your motorcycle will
require some preventive proce-
dures to guard against deteriora-
tion. After thoroughly cleaning the
motorcycle, prepare for storage as
follows:
1. Fill the fuel tank with fuel and
add fuel stabilizer (if available).
2. Remove the spark plug, pour
about one tablespoon of SAE
10W30 or 20W40 motor oil in
the spark plug hole and rein-
stall the spark plug. Turn the
engine over several times
(ground spark plug lead) to
coat the cylinder wall with oil.
EW000127
w
When using the starter motor to
crank the engine, remove the
spark plug wires, and ground them
to prevent sparking.
3. Thoroughly clean and lubricate
the drive chain. (For details,
see “Drive chain lubrication”
on page 6-23.)
4. Lubricate all control cables.
5. Block up the frame to raise
both wheels off the ground.
6. Tie a plastic bag over the
exhaust pipe outlet to prevent
moisture from entering.
7. If storing in a humid or salt-air
atmosphere, coat all exposed
metal surfaces with a light film
of oil. Do not apply oil to any
rubber parts or the seat cover.
8. Remove the battery and
charge it. Store it in a dry place
and recharge it once a month.
Do not store the battery in an
excessively warm or cold place
(less than 0°C or more than
30°C.
NOTE:
Make any necessary repairs before
storing the motorcycle.
