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.

    This is gonna sound like a stupid question but would old oil or low oil cause the forks to want to bottom out when coming to a stop or hitting a bump to hard
