Brakes
Replacement of brake components requires pro-
fessional knowledge. Brake service should be per-
formed by a Yamaha dealer.

Operating with improperly serviced or adjust-
ed brakes could lead to a loss in braking ability
and an accident.

Brake fluid replacement

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 hoses every four years.

Checking the brake pedal
Have a Yamaha dealer check the brakes at the in-
tervals specified in the periodic maintenance 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.

Troubleshooting
Although Yamaha vehicles receive an inspection
before shipment from the factory, trouble may oc-
cur during operation. Any problem in the fuel, com-
pression, or ignition systems can cause poor
starting and loss of power. The troubleshooting
chart describes a quick, easy procedure for mak-
ing checks. If your vehicle requires any repair, take
it to a Yamaha dealer.
The skilled technicians at a Yamaha dealership
have the tools, experience, and know-how to prop-
erly service your vehicle. Use only genuine
Yamaha parts on your vehicle. Imitation parts may
look like Yamaha parts, but they are often inferior.
Consequently, they have a shorter service life and
can lead to expensive repair bills.
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 heaters or furnaces. Gasoline or gaso-
line vapors can ignite or explode, causing se-
vere injury or property damage.
