I am coming upon the 50 hour hydro oil change on my Super Z and was checking out my options. The filter is 60 something dollars and it takes 3 gallons of oil, Mobil 1. I need to save some money and try to do it my self. What is the procedure? Do I work the wheels to get the oil out of the pumps and wheel motors? I'm pretty mechanically inclined with dozens of motorcycles but I haven't done a hydro oil change before.
