Bob and Mark demonstrate the best way to empty Harley fork oil from your Sportster’s front fork sliders and replace it with new oil. It can be a two-man job, so try to complete the service with a friend. Newer bikes mostly use 39-millimeter forks, but most bikes are preset with varying levels of spring in the sliders, so consult your manual before you begin this service. Like any other service, you should clean all of the parts that you remove with parts cleaner to ensure that your bike operates smoothly between services.
Bob and Mark demonstrate the process for lubricating your Harley’s steering head bearings and adjusting the fall-away. As always, Bob stresses the importance of adequately prepping all bolts, consulting your user manual to be sure everything is done correctly, covering any painted areas on the bike and, if possible, working with two sets of hands.
Bob walks us through Harley rear wheel alignment. He’ll just loosen the rear axle nut and with a homemade tool he’ll measure the proper distance and adjust accordingly. Next Video: Rear Shock Adjustment and Drive Belt Service
