Check Alignment
WARNING
The automatic-on headlamp feature provides increased visibility of the rider to other motorists. Be sure headlamp is on at all times. Poor visibility of rider to other motorists can result in death or serious injury. (00030b)
  1. Verify correct front and rear tire inflation pressure. Refer to Specifications → Tire Data: FLHTCUSE → Tire Pressures: 2006 FLHTCUSE.
  2. Place the motorcycle on a level floor or pavement in an area with minimum light.
  3. See Figure 1. Point the front of the motorcycle toward a screen or wall which is 25 feet (7.6 meters) from where patch of front tire contacts floor (i.e. - directly below front axle).
  4. Draw a horizontal line on screen or wall (1) that is exactly the same height above the floor as the headlamp center.
  5. Have a person whose weight is roughly the same as that of the principal rider sit on the motorcycle seat. The weight of the rider will compress the vehicle suspension slightly.
  6. Stand the motorcycle upright with both tires resting on the floor and with the front wheel held in straight alignment (directly forward).
  7. Turn the ignition/headlamp key switch to IGNITION. Set the Light Switch on the left handlebar to Hi(gh) beam.
  8. Verify and correct headlamp adjustment if necessary.
    1. Check the light beam for proper height alignment. The center of the main beam of light should be even with the horizontal line on the screen or wall.
    2. Check the light beam for proper lateral alignment. The main beam of light should be directed straight ahead (i.e., equal area of light to right and left of center).
