Im not sure I understand. Are you filling the fork from the drain plug end or schrader valve? I dont see how the fork would fill up from the schrader valve with the drain plug installed. I think im missing something.

This is how I understand his description. You connect the mighty vac to the schrader valve. While pumping the mighty vac, you draw the oil into the fork through the drain hole which now has the tapered fitting inserted in it with a hose going into a container of new fluid. You would continue to pump the mighty vac until the new fluid has drawn up into the fork, then you replace the tapered fitting with your original plug, thus allowing little to none of the fork oil draining out. Probably much easier with a helper, unless you draw in an extra ounce and stop pumping while you replace your plug.
Sound right to you? Guess I need to visit Harbor Freights for a mighty vac. :-)

Damn that sounds complicated.
All I do is remove the fork cap, remove drain plug, after the fluid is out install drain plug, then fill through the hole in the top and replace the fork cap.

From the picture in your avatar it looks like you have to take off your windshield, what else do you have to take off to get to the fork cap??
