Adjustments to steering head bearings should be performed by a Harley-Davidson dealer. Improperly adjusted bearings can adversely affect handling and stability, which could result in death or serious injury. (00051b)
Refer to Maintenance Scheduling → Regular Service Intervals → Regular Service Intervals: 2006 Sportster Models. Check front fork for proper bearing adjustment and lubricate bearings at proper intervals.
With motorcycle front end raised off the floor, be sure front fork turns freely without any binding or interference and that there is no appreciable front to rear fork shake indicating excessive bearing looseness. Steering head bearings should be adjusted according to Service Manual procedure, if necessary.
