Elevate the motorcycle front tire off the ground slightly and turn handlebars through their full range of steering travel several times to check for smooth damper action. Check all damper mounting fasteners for tightness.
The steering damper must be replaced or rebuilt at specified intervals. If steering damper leaks or is damaged, see a Harley-Davidson dealer.
