working properly.
8A soft or spongy feeling in the
brake lever can indicate the
presence of air in the brake
system. This air must be
removed by bleeding the
brake system before the
motorcycle is operated. Air in
the system will cause greatly
diminished braking capability
and can result in loss of con-
trol and an accident. Have a
Yamaha dealer inspect and
bleed the system if necessary.
