Front brake pad inspection
Each brake pad is provided with a wear indicator
groove. The indicator grooves allow checking of
brake pad wear without disassembling the
brake. Apply the brake and inspect the wear
indicator grooves. If a brake pad is worn to the
point that the wear indicator groove is almost in
contact with the disc plate, ask a Yamaha dealer
to replace the brake pads as a set.
NOTE:
The wheels need to be removed to inspect the
brake pads. (See page 8-125 for wheel removal
and installation procedures.)

5. Screw in the adjusting bolt at the rear
brake caliper by hand until it feels tight,
then screw it out 1/8 turn. Tighten the lock-
nut to the specified torque.

When tightening the locknut, hold the adjust-
ing bolt with a wrench so that the adjusting
bolt does not turn together with the locknut.

Operating with improperly adjusted brakes
could cause the brakes to malfunction, result-
ing in reduced braking performance. This
could increase the chance of a collision or
accident. After adjusting the parking brake,
block the rear of the machine off the ground
and spin the rear wheels. Check to make sure
there is no brake drag. If brake drag is noticed,
perform the adjustment again.

CLEANING AND STORAGE
A. CLEANING
Frequent, thorough cleaning of your machine
will not only enhance its appearance but will
improve its general performance and extend the
useful life of many components.
1. Before cleaning the machine:
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 gar-
den hose. Use only enough pressure to do
the job.

cC
Excessive water pressure may cause water
seepage and deterioration of wheel bearings,
brakes, transmission seals and electrical
devices. Many expensive repair bills have
resulted from improper high pressure deter-
gent 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 machine 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.

4. Lubricate all control cables.
5. Block up the frame to raise all wheels off
the ground.
6. Tie a plastic bag over the exhaust pipe out-
let 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
machine.
