STEERING
The steering should be adjusted properly for smooth turning of
the handlebars and safe operation. Overtighten steering pre-
vents smooth turning of the handlebars and too loose steering
will cause poor stability. Check that there is no play in the front
fork. Support the motorcycle so that the front wheel is off the
ground. With the wheel facing straight ahead, grasp the lower
fork tubes near the axle and pull forward. If play is found, read-
just the steering. (
