EBU35170Brake and clutch fluid replacementComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during periodic maintenance or
when they are damaged or leaking.
Replace the oil seals every two years.
 Replace the brake and clutch hoses every
four years.EBU35182Checking the clutch pedalThe clutch pedal should operate smoothly
and spring back to position when released.
When depressed, it should offer resistance
before reaching the floorboard. If the pedal
offers little resistance when depressed, or if
the transmission grinds gears when shifting,
have a Yamaha dealer check the vehicle.
TIPDon’t forget to have your Yamaha dealer
check the clutch and transmission as a whole
at the intervals specified in the periodic main-
tenance chart. EBU32531Checking the brake pedalHave a Yamaha dealer check the brakes at
the intervals specified in the periodic mainte-
nance chart. There should be no free play in1. Clutch pedal

the brake pedal. The brakes should operate
smoothly and there should be no brake drag.
If the brakes feel soft or spongy, this could in-
dicate air in the brake system. Have a
Yamaha dealer check the brake system if
necessary.
EBU35821Checking the accelerator pedalThe accelerator pedal should operate
smoothly and spring back to position when
released. If the pedal free play is out of spec-
ification, have a Yamaha dealer adjust or re-
place the throttle wire.

sary, adjust the free play as follows.
3. Remove panel B. (See page 9-10.)
4. Release the parking brake lever. 5. Slide the rubber cover back on the park-
ing brake cable.
6. Loosen the locknut.

the brake pedal, is properly adjusted when
the brake light comes on just before braking
takes effect.
If necessary, adjust the brake light switch.1. Hold the brake light switch in place.
2. Turn the adjusting nut in direction (a) to
make the brake light come on earlier.
3. Turn the adjusting nut in direction (b) to
make the brake light come on later.
EBU35930Cable inspection and lubrication
WARNING
EWB03380Damaged cables could restrict operation,
which may cause an accident or injury. In-
spect control cables frequently and re-
place damaged cables. Corrosion can
result when the outer covering of control
cables becomes damaged. Cables can
also become frayed or kinked. Lubricate the cable ends. If the cables do not
operate smoothly, ask a Yamaha dealer to re-
place them.

EBU35200Pedal lubricationThe pivoting parts of the brake, clutch, and
accelerator pedals should be lubricated peri-
odically to prevent rust and ensure smooth
operation.
EBU32583Checking the stabilizer bushesThe stabilizer bushes must be checked for
cracks or damage at the intervals specified in
the periodic maintenance chart. Have a
Yamaha dealer replace the stabilizer bushes if necessary.

EBU37910Brake/tail lightThis model is equipped with an LED brake/tail
light, there are no replaceable bulbs.
If the brake/tail light does not come on, check
for a loose connection, check the fuses, and
then have a Yamaha dealer check the vehicle.EBU32700TroubleshootingAlthough Yamaha vehicles receive an inspec-
tion before shipment from the factory, trouble
may occur during operation. Any problem inthe 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 vehicle
requires any repair, take it to a Yamaha deal-
er.
The skilled technicians at a Yamaha dealer-
ship have the tools, experience, and know-
how to properly service your vehicle. Use only
genuine Yamaha parts on your vehicle. Imita-
tion parts may look like Yamaha parts, but
they are often inferior. Consequently, they
have a shorter service life and can lead to ex-
pensive repair bills.
WARNING
EWB03450When checking the fuel system, do not
smoke and make sure there are no open
flames or sparks in the area, including pilot
lights from water heaters or furnaces.

CLEANING AND STORAGE
EBU35920CleaningFrequent, 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 plugs 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]
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 vehicle off immediately with
clean water and dry all surfaces with a
clean chamois towel or soft, absorbent
cloth.
6. Clean the seats with a vinyl upholstery cleaner to keep the covers pliable and
glossy.
