CAUTION:
1. Do not coast for long periods with the engine off,
and do not tow the motorcycle a long distance. Even
with gears in neutral, the transmission is only
properly lubricated when the engine is running.
Inadequate lubrication may damage the
transmission.
2. Always use the clutch when changing gears. The
engine, transmission, and driveline are not
designed to withstand the shock of forced shifting
and can be damaged by shifting without using the
clutch.
Shifting
The transmission lets you control the amount of power you
have available at a given speed for starting, accelerating,
climbing hills, etc. The use of shift pedal is shown in the
illustration (page 3-6).
To shift into NEUTRAL, depress the shift pedal repeatedly
until it reaches the end of its travel (you will feel a stop
when you are in first gear), then raise the pedal slightly.

7-1 A. 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 components.
1. Before cleaning the motorcycle:
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 excessively 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.
CAUTION:
Excessive hose pressure may cause water seepage and
deterioration of wheel bearings, front fork, brakes,
transmission seals and electrical parts.
Many expensive repair bills have resulted from
improper high pressure detergent applications such as
those available in coin-operated car washers.
4. 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.
5. Rinse the motorcycle off immediately with clean water
and dry all surfaces with a chamois, clean towel, or
soft absorbent cloth.
6. Dry the chain and lubricate it to prevent rust.
7. Clean the seat with a vinyl upholstery cleaner to keep
the cover pliable and glossy.
8. 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 protective finish. When finished, start the engine and
let it idle for several minutes.
