You need two items that are pretty much required. I use the Pitbull rear stand to support the bike while pumping the old oil out and some sort of jack, like a bottle jack to support the bike under the pipes when you take off the top caps of the fork tubes. So with catchpans under the fork tubes, take the compression fitting out of the bottom of the fork tubes, 17 mm. Making a big mess with the bike on it's rear stand, pump all the oil out of the forks. I used a large disposable syringe to get the last of the oil out of the compression fitting cup.
When you're happy with that, jack up the front of the bike and back off all of the fork spring preload, 17mm. Back off the allen heads that hold the top of the fork tubes, and then use a pin wrench [I used the one that came with an angle grinder] to remove the fork caps, they should be hand tight only. They will be fully loose when you hear them clicking.
At this point, lower the front of the bike until the top of the fork spring is revealed as the cap pops up. I had to remove my handlebars because I have risers that interfered with the caps and I'm not sure if that will happen without them. Reinstall the compression fittings and with a suitable funnel, pour the new oil in from the top. I used Redline "water weight fluid" and poured the contents of the bottle, 1 pt. into each leg, 2 pts. total. That's slightly less than the factory fill. Jack the front of the bike back up and rethread the fork caps and reset the spring preload. And as my Blighty friends say, Bob's your Uncle!!
