PERIODIC MAINTENANCE AND ADJUSTMENT

7-16

7

Tire inspection

The tires must be checked before each
ride.

NOTICE

ECA15580

Be sure the bead stoppers are
tightened. Loose bead stoppers
will cause the tire to slip off the
rim if tire pressure is too low.

Be sure the valve stem is posi-
tioned straight. A tilted valve
stem indicates that the tire has
slipped from its original posi-
tion on the rim. Rotate the tire
so that the valve stem is posi-
tioned straight.

If the center tread depth reaches the
specified limit, if the tire has a nail or
glass fragments in it, or if the sidewall is
cracked, have a Yamaha dealer re-
place the tire immediately.

Tire information

This motorcycle is equipped with spoke
wheels and tube tires.
