EBU32460Valve clearanceThe correct valve clearance changes with
use, resulting in improper fuel/air supply or
engine noise. To prevent this, the valve clear-
ance must be adjusted regularly. This adjust-
ment however, should be left to a
professional Yamaha service technician.EBU32470BrakesReplacement of brake components requires
professional knowledge. Brake service
should be performed by a Yamaha dealer.
WARNING
EWB02572Operating with improperly serviced or ad-
justed brakes could lead to a loss in brak-
ing ability and an accident.
EBU32480Checking the front and rear brake padsEach brake pad is provided with wear indica-
tor grooves, which allow you to check the
brake pad wear without having to disassem-
ble the brake. To check the brake pad wear,
check the wear indicator grooves. If a brake
pad has worn to the point that the wear indi-
cator grooves have almost disappeared, have
a Yamaha dealer replace the brake pads as a
set.
The wheels need to be removed to check the
brake pads. (See pages 8-40, 8-42 for wheel
removal and installation procedures.)

As the brake pads wear, it is normal for the
brake fluid level to gradually go down. A low
brake fluid level may indicate worn brake
pads and/or brake system leakage; therefore,
be sure to check the brake pads for wear and
the brake system for leakage. If the brake fluid
level goes down suddenly, have a Yamaha
dealer check the cause before further riding.EBU32520Brake fluid replacementComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during pe riodic maintenance or
when they are damaged or leaking.
 Replace the oil seals every two years.
 Replace the brake hoses every four years.EBU32530Checking the brake pedalHave a Yamaha dealer check the brakes at
the intervals specified in the periodic mainte-
nance and lubrication chart. There should be no free play in the brake pedal. The brakes
should operate smoothly
and there should be
no brake drag. If the brakes feel soft or
spongy, this could indicate air in the brake
system. Have a Yamaha dealer check the
brake system if necessary.
EBU32540Parking brake lever free play adjust-
mentPeriodically check the parking brake lever
free play and adjust it if necessary.1. Brake pedal

CLEANING AND STORAGE
EBU32731CleaningFrequent, thorough cleaning of your vehicle
will not only enhance its appearance but will
improve its general performance and extend
the useful life of many components.1. Before cleaning the vehicle: a. Block off the end of the exhaust pipeto 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 wheel axles.
3. Rinse the dirt and degreaser off with a garden hose. Use only enough pressure
to do the job. WARNING! Test the
brakes after washing. Apply the
brakes several times at slow speeds to
let friction dry the brakes. Wet brakes may have reduced stopping ability, in-
creasing the chance of an accident.
[EWB03471]

NOTICE: Excessive water pres-
sure may cause water seepage and
deterioration of wheel bearings,
brakes, transmission seals and electri-
cal devices. Many expensive repair
bills have resulted from improper high-
pressure detergent applications such
as those available in coin-operated car
washers.
[ECB00712]
TIPThe tailgate can be removed to make it easier
to clean the cargo bed. To separate the tail-
gate from the cargo bed, unhook the latches,
lift the left side of the tailgate and pull the tail-
gate to the left. 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.
