I won't take pictures and give away all of my secrets...
But
you can make an engine cradle which attaches to the front of your motor...this will allow you to drop the motor without removing ANY of the fluids. Basically you attach the cradle, remove the motor mounts, shift the motor out of the mounts, route your front and rear wiring to the motor...then either lift the roller off intact...or remove your front forks and then you can lift the chassis and use the rear wheel like a wheel barrel.
You can make the cradle out of wood if you like (my first one was)
Put the bike on a rear lift...the attachment points on the motor are lower front and you want two legs to go back and just rest under the rear block. From the side it looks like an L with small uprights on the rear for the rear block to rest on.
The only thing that will need cut/removed is the chain.
