Steering inspectionPeriodically inspect the condition of the
steering. Worn out or loose steering
bearings may be dangerous. Place a
stand under the engine to raise the
front wheel off the ground. Hold the
lower end of the front forks and try to
move them forward and backward. If
any free play can be felt, ask a Yamaha
dealer to inspect and adjust the steer-
ing. Inspection is easier if the front
wheel is removed.

there is no danger of it falling over. @
