Harbor Freight sells a
scissor jack for $15. You can weld or bolt a rectangular piece of sheet metal to the jack head to make a very nice jack for the FJR. Or use a scrap of wood temporarily. Nice thing about scissor jacks is you don't have to worry about them leaking down overnight.
I highly recommend removing the front fender for a Gen-II tire change. It makes the job much easier and there's significantly less risk of paint damage.
One final recommendation... Hang something like a red flag on the front brake handle, each and every time you begin a tire change. That will remind you of that final, most important step to pump the caliper pistons back into position before riding the bike. I use one of the "REMOVE BEFORE FLIGHT" flags.
