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 demonstrates how to service the front and rear brake calipers on a Sportster. There are a few changes that Harley has made over the years, so you should be sure to pay attention to the differences; they could affect how you service your bike.
In order to service the fuel filter on your Sportster, you’ll need to drain the fuel tank. Bob demonstrates the best way to do this using a MityVac and a gasoline can. Once you follow his instructions and drain the fuel tank filter, cleaning any dirty parts and tightening any loose bolts, you can refill the tank with fuel and your bike should be good to go.
