Don't know if anyone has ever considered this but, it's easy to pull the frame from the engine.
Remove as much as you can on just the center stand or a few paddock stands (wheels, headers, fluids, etc) > attach some (or more like a lot of) thick blankets (or even some thick pillows, etc) to the side of the engine/frame > put a mattress on the floor on that same side > roll bike onto mattress > lift frame off of engine

 

just as a sort of disclaimer.....it's much better to have the right tools to do the job right. My suggestion might work but it's not the correct method nor are the tools used the correct ones. It's just an alternate and perhaps a cheap (depending on what you have laying around) way of doing it.

P.S. installation is the reverse of removal lol
