Chapter 7 (Running Gear)
Steering Head Bearings
The steering head bearings must be adjusted periodically to avoid
excessive play which might cause steering instability. When
properly adjusted the front fork should turn with just a hint of
bearing drag, but not free play or obvious resistance to turning.
WARNING: Improper adjustment of the steering head (e.g. too
tight) will make the motorcycle very difficult to steer. This
adjustment is critical for proper handling of all models.
