If you weren't 3500 miles away from me, I would say come on up to my place, and I will show you how to do everything on your bike, as I love instructing riders how to be mechanically self-sufficient.
Do you have a bench vise in your garage or shop? Try spraying the tire, at the seam to the wheel, with WD-40, and letting it sit for a few hours.
Given that this is a tube type tire, it generally is NOT hard to break that bead, and release the tire from the wheel.
The sidestand from your FZ-1 will work, if you find nothing else. Using a car jack, on top of the rear tire, while the tire is laid flat, and then jacking the car jack UP under your car, so in essence you are using the car jack to push DOWN onto the bike's rear tire, that could also serve as a leverage point.
