NOTE:
Pre-operation checks should be made each time the motorcycle is used. Such an inspection can be accomplished in a
very short time; and the added safety it assures is more than worth the time involved.

If any item in the Pre-Operation Check is not working properly, have it inspected and repaired before operating
the motorcycle.

A soft or spongy feeling in the
brake pedal can indicate the pres-
ence of air in the brake system.
This air must be removed by
bleeding the brake system before
the motorcycle is operated. Air in
the system will cause greatly
diminished braking capability and
can result in loss of control and an
accident. Have a Yamaha dealer
inspect and bleed the system if
necessary.

Brake light switch
adjustment
The rear brake light switch is activat-
ed by the brake pedal and is properly
adjusted when the brake light comes
on just before braking takes effect.
To adjust the rear brake light switch,
hold the switch body so it does not
rotate while turning the adjusting nut.
Turn the adjusting nut in direction a
to make the brake light come on earli-
er.
Turn the adjusting nut in direction b
to make the brake light come on
later.

brake pads

Front brake
A wear indicator groove is provided
on each brake pad. This indicator
allows checking of brake pad wear
without disassembling the brake.
Inspect the groove. If the groove has
almost disappeared, ask a Yamaha
dealer to replace the pads.

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 plastic.
8 8
Do 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, sol-
vent or thinner, fuel (gasoline),
rust removers or inhibitors,
brake fluid, antifreeze or elec-
trolyte.8 8
Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the
following areas: seals (of
wheel bearings, swingarm
bearings, forks and brakes),
electric components (cou-
plers, connectors, instru-
ments, switches and lights),
breather hoses and vents.
8 8
For motorcycles equipped
with a windshield: Do not use
strong cleaners or hard
sponges as they will cause
dulling or scratching. Some
cleaning compounds for plas-
tic may leave scratches on the
windshield. Test the product
on a small hidden part of the
windshield to make sure they
do not leave any marks. If the
windshield is scratched, use a
quality plastic polishing com-
pound after washing.After riding in the rain, near the sea
or on salt-sprayed roads
Since sea salt or salt sprayed on the
roads in the winter are extremely cor-
rosive in combination with water,
carry out the following steps after
each ride in the rain, near the sea or
on salt-sprayed roads. (Salt sprayed
in the winter may remain on the roads
well into spring.)
1. Clean your motorcycle with cold
water and soap after the engine
has cooled down.
ECA00012
cC
Do not use warm water since it
increases the corrosive action of
the salt.
2. Be sure to apply a corrosion pro-
tection spray on all (even
chrome- and nickel-plated) metal
surfaces to prevent corrosion.
