6-41 Troubleshooting
Although Yamaha motorcycles receive a rigid inspection
before shipment from the factory, trouble may occur during
operation. Any problem in the fuel, compression, or ignition
systems can cause poor starting and loss of power. The
troubleshooting chart describes a quick, easy, procedure
for making checks. If your motorcycle requires any repair,
bring it to a Yamaha dealer. The skilled technicians at a
Yamaha dealership have the tools, experience, and know-
how to properly service your motorcycle. Use only genuine
Yamaha parts on your motorcycle. Imitation parts may look
like Yamaha parts, but they are often inferior. Consequently,
they have a shorter service life and can lead to expensive
repair bills.

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.
