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 9-56, 9-57 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

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

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.
