1.   Move forks from stop to stop to check for smooth operation.
     Rough operation indicates damaged bearings. See                  2.   See Figure 2-20. Loosen fork stem pinch screw (3).

1.   H ave a helper position motorcycle vertical with steering
     straight.                                                             Torque: 15-18 ft-lbs (20.4-25 N·m) Fork bracket, upper

2.   Measure fork angle.
                                                                      8. Repeat measure and adjust as needed.

     a.    Measure fork angle on a vertical bike (steering
           straight).                                                            Table 2-11. Pull Force Specifications
                                                                                   MODEL                    MINIMUM    MAXIMUM
     b.    Raise motorcycle. See Secure the Motorcycle for                                                      3         6

     c.    Make sure the fork angle is the same lifted as it was
           on the ground.

     d.    Use a suitable cell phone app or angle finder
           accurate within a degree or two.

3.   Perform test.

     a.    Move handlebars from left to right steering stops
           three times, ending at full left steering stop.

     b.    Using a 0-25 lbs pull force scale with a peak hold
           feature, pull from the inside diameter of the front axle
           until the front end is straight.
                        NOTE
See Figure 2-18. While pulling, keep scale parallel
to front tire and perpendicular to fork leg.

Be sure to pull slowly without tugging the scale.                                 Figure 2-18. Pull Force Orientation

     c.    Repeat steps a and b until the peak force value
           becomes consistent.

4.   If peak force value is not within specification, adjust the
     fork stem screw. Refer to Table 2-11.
