WARNING
EWB02572Operating with improperly serviced or ad-
justed brakes could lead to a loss in brak-
ing ability and an accident. EBU35150Checking the front and rear brake padsCheck each brake pad for damage and mea-
sure the lining thickness. If a brake pad is
damaged or if the lining thickness is less than
1.0 mm (0.04 in), have a Yamaha dealer re-
place the brake pads as a set.
The wheels need to be removed to check the
brake pads. (See pages 9-57, 9-59 for wheel
removal and installation procedures.)
EBU32490Checking the parking brake padsEach brake pad is provided with a wear indi-
cator groove, which allows you to check the
brake pad wear without having to disassem-
ble the brake. If a brake pad has worn to the
point that the wear indicator groove has al-
most disappeared, have a Yamaha dealer re-
place the brake pads as a set.1. Lining thickness

EBU36610Checking the brake and YCC-S clutch
fluid levelsBefore starting off, check that the brake and
YCC-S clutch fluids are above the minimum
level marks. Replenish the brake and YCC-S
clutch fluids if necessary.
TIPThe brake and YCC-S clutch fluid reser-
voirs are located under the hood (page
9-11).
 For an accurate reading, make sure the ve-
hicle is parked on a level surface.

WARNING
EWB04160Improper maintenance can result in loss of
braking ability or YCC-S clutch operation.
Observe these precautions:
Insufficient brake or YCC-S clutch fluid
may allow air to enter the brake or
YCC-S clutch system, reducing braking
or YCC-S clutch performance.
 Clean the filler caps before removing.
Use only DOT 4 brake fluid from a sealed
container.
 Use only the specified brake fluid; other-
wise, the rubber seals may deteriorate,
causing leakage.
 Refill with the same type of brake fluid.
Adding a brake fluid other than DOT 4
may result in a harmful chemical reac-
tion. 
Be careful that water or dust does not
enter the brake or YCC-S clutch fluid
reservoir when refilling. Water will signif-
icantly lower the boiling point of the fluid
and may result in vapor lock.
NOTICEECB01161Brake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
fluid immediately. 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 or brake system leakage; therefore, be
sure to check the brake pads for wear and the
brake system for leakage. A low YCC-S
clutch fluid level may indicate YCC-S clutch
system leakage; therefore, be sure to check
the YCC-S clutch system for leakage. If the
brake or YCC-S clutch fluid level goes down

suddenly, have a Yamaha dealer check and
repair the vehicle before any further opera-
tion.EBU36550Brake and YCC-S clutch fluid replace-
mentComplete 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 YCC-S clutch hoses
every four years.EBU36540YCC-S clutchThis model is equipped with a hydraulic
clutch, therefore, it is necessary to check the
YCC-S clutch fluid level and check the hy-
draulic system for leak age before each drive.
If the YCC-S clutch plates wear out, shifting
becomes rough or clutch slippage will occur, causing poor acceleration. If any of the above
occurs, have a Yamaha dealer check the
YCC-S clutch.
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 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 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.
EBU35194Parking brake lever free play adjust-
mentPeriodically check the parking brake lever
free play and adjust it if necessary.1. Shift the transmission into first gear.
2. Check the parking brake lever free play.
The maximum free play is equal to one
click of the parking brake lever. If neces-
sary, adjust the free play as follows.

EBU36620Brake light switchThe brake light, which is activated by the
brake pedal, should come on just before
braking takes effect. Since the brake light
switch is a component of the YCC-S system,
it must be adjusted by a Yamaha dealer, who
has the necessary professional knowledge
and experience.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.EBU36760Pedal lubricationThe pivoting parts of the brake and accelera-
tor pedals should be lubricated periodically to
prevent rust and ensure smooth operation.Recommended lubricant:Yamalube LubezAll (synthetic lubricant spray with PTFE)

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.EBU36961Interior lights (equipped models)This model is equipped with LED interior
lights. There are no user replaceable bulbs.
If one or more interior lights do not come on,
check for a loose connection, check the fus-
es, 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 in
the fuel, compression, or ignition systems can
cause poor starting and loss of power. The
troubleshooting chart describes a quick, easyprocedure 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.
Gasoline or gasoline
vapors can ignite or
explode, causing severe injury or property
damage.

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.
