Tonti is pretty east to put a clutch in. Tank off, Pull the swingarm, wheel in if you have the hands. Trans top mount, loosen the front mounts. A few fasteners here and there like the battery box. Be sure anything strapped too tightly to the frame is released, and pull the frame up far enough to get at it. Starter, ground wire to the trans (hopefully, if not put one) Of course, you have to stabilize and secure the front wheel and block the motor sufficiently to wiggle the frame 'off'- unless you're stronger than I am you'll want some sort of hoisting mechanism to a rafter (in my case, open garage door braces on a 600lb hurricane rated door) as the whole event gets less than stable as it goes up. The only special tool you'll need is a clutch alignment tool. I'm pretty sure there are complete writups with photos on Wildguzzi.com.
As for releasing the stuck plates, everything will come to hand easily enough, then you can attack it on the bench with increasing zeal and chemistry until it's apart.
