using grease and insert the steering stem from the

(CAUTION)
a. When the. steering stem is being inserted by
using new grease, insure that the steel balls are
not dropped.
b. Special experience and skill is required for
tightening the head top thread (complete).
When the steering stem is slightly tightened
and the front cusion, fender, and wheel are
installed, the fork top bridge is tightened by the
front fork bolt and head stem nut. The top
thread is fully returned and the stem should be
tightened to the extent that there is no play,
but is not stiff. The weight of the steering
stem should be such that, when the front wheel
is suspended in air, the wheel falls by its own
weight when a slight force is exerted. When
the front wheel is moved forward, backward,
laterally, and vertically, there should be no play
at the race section.
3. Install the front cushion and front wheel.
