1. Wear indicator
2. Wear limit lineThe front and rear brake shoes must be
checked for wear at the intervals speci-
fied in the periodic maintenance and lu-
brication chart. Each brake is provided
with a wear indicator, which allows you
to check the brake shoe wear without
having to disassemble the brake. To
check the brake shoe wear, check the
position of the wear indicator while ap-
plying the brake. If a brake shoe has
worn to the point that the wear indicator
reaches the wear limit line, have a
Yamaha dealer replace the brake shoes
as a set.

WARNING
When 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 heat-
ers or furnaces. Gasoline or gasoline
vapors can ignite or explode, caus-
ing severe injury or property damage.
EAU25881
TroubleshootingAlthough Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur dur-
ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting charts rep-
resent quick and easy procedures for
checking these vital systems yourself.
However, should your scooter require any
repair, take it to a Yamaha dealer, whose
skilled technicians have the necessary
tools, experience, and know-how to ser-
vice the scooter properly.
Use only genuine Yamaha replacement
parts. Imitation par ts may look like
Yamaha parts, but they are often infe-
rior, have a shorter service life and can
lead to expensive repair bills. Troubleshooting

8Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.

8Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the
detent to allow any residual pressure to escape. When the hissing sound has stopped, press down on the cap
while turning it counterclockwise, and then remove the cap.TIP
If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolant
as soon as possible.
