Have you experimented in the past with lifting the engine out the side with a come along? Putting any motorcycle on its side smacks of preloading bad karma haha.

There's a long rod going through the gearbox that gets in the way if you don't pull it out.
The engine's only held in with the 2 rods at the bottom(yours might have the mounts on top that go to the starter cover too). You might be able to lay the bike over and lift the engine out the side with a come-along.
