Brake fluid replacement

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.

oil in the spark plug hole and reinstall the
spark plug. Ground the spark plug wire and
turn the engine over several times to coat the
cylinder wall with oil.
3. Lubricate all control cables.
4. Block up the frame to raise all wheels off the
ground.
5. Tie a plastic bag over the exhaust pipe outlet
to prevent moisture from entering.
6. If storing in a humid or salt-air atmosphere,
coat all exposed metal surfaces with a light
film of oil. Do not apply oil to any rubber parts
or the seat covers.
7. Remove the battery and charge it. Store it in
a dry place and recharge it once a month. Do
not store the battery in an excessively warm
or cold place [less than 0°C (30°F) or more
