Who has made a floor standing crutch for the rear of their brick..Ive seen the saw horses and ropes slung over rafters, either of which I could do, but why not a purpose build stand?
1) With the bike on the center stand, take off the rear wheel, final drive (being sure to support the swing arm so as not to tear the rubber boot) and swing arm and drive shaft (there's a bit more to it than that, but the steps will be obvious enough).
2) Take out the "brain" (computer) that lives under the saddle. Refer to your Haynes or Clymer to show you how to unplug the huge connector.
3) Put one sawhorse on either side of the bike, with the tops of the sawhorses parallel to the length of the bike.
4) Slip a 2x4 through the space in the frame where the brain was. Have someone help you place one end of the 2x4 on each sawhorse. In the process you will lift the center stand off the floor.
5) You are now free to remove the center stand and pull the transmission (especially if you put enough space between the sawhorses).
