The fork oil is a very specific job needing a manual and a special tool, I don't want to insult anyones mechanical knowledge but if you have never done it before, best to take somewhere else. Engine oil on the other hand is easy, the drain tube to any softail is on the right side by where the frame meets the swing arm, has somekind of plug in it. Start and run bike for a little while, long enough to get it warm but not hot. Remove fill plug and then remove plug in drain line. Using a peice of cardboard or something put in between filter and frame , directing the oil to your drain pan instead of where ever it goes. Put 1 qt oil back in (after everything is reinstalled) start the bike and make sure the oil light goes out, when it does shut bike off and fill to the point that when it is standing upright you get a little oil on the tip of your finger, over filling may result in loss of oil cap from pressure (been there)

On your oil tank, there are three hoses. The hose that comes off the lower fitting goes to the outside fiiting on the top of the pump or to the center fitting of the pump top plate. The oil comes out of the inner fitting on the pump and goes to the oil filter. It should to to the outside holes of the filter. The oil leaves the filter though the large hole in the center and returns to the tank to one of the fittings at the top of the tank. The other fitting at the top of the tank comes for the engine case just above and to the inside of the oil pump. On the lower backside of the oil tank is the oil drain hose. If you're unsure which fitting on your oil pump is the inlet and which is the outlet, squirt a bit of oil into each fitting until it's full. Then press the start button or rotate the engine in it's normal direction of rotation and watch the oil. If the oil is sucked into pump, that's the inlet. If it's pumped out of the pump, that's the outlet. Sorry I don't have a picture. There is a drawing in the service manuals.

Good Luck
