Thank you for the tips!
I am going to look for a bicycle pump like Bucko suggests, and set it with a gauge, like Kawboy said.
Biltonjim - They are going to be pressed on the wheels tomorrow. I will post pictures. Wheels are ready with new bearings and seals, and all painted and cleaned, including one part chromed.
With the unusual circumstances of my build, I need to make a plan. The bike can't fit in the elevator fully assembled. The plan is to fully assemble it at my place including wheels and everything., including battery so I can test the lights. The starter works, the solenoid works, so I am sure the engine will turn. I am not going this far here though, and I will not be putting oil nor coolant in the bike before taking it down.
The rough plan is to remove the front forks and the wheel, remove the rear shock, unscrew and align with the bike the handlebar, remove the seat, the tail light with the cowling and the fender, remove the turn signals. I will be mocking up the oil pan, but probably not attaching it permanently. It's easier to place the bike on a flat surface than with the oil pan in place.
I will build a custom dolly from 2x4 and 3/4 inch plywood with four caster wheels and pieces of wood screwed down to keep the bike in place. Tie down the bike to it with straps so it want move when pushing it by holding the frame. It will be about the same size as when I brought it here and will fit in the elevator this way. If I'd decide to bolt on the oil pan permanently, I'd just add more space between the bike and the dolly to keep the distance. I am just not too keen on having the gravity center too far from the ground. There is also the issue of the exhaust pipes - I'd rather not risk having them squashed so I'd prefer having them off for transport.
Once out of the hiding, I would bring the removed parts and having everything already prepared, putting them back on the bike would be an already rehearsed routine and should take no time. Wheels, lights, pipes, and the oil pan.
Next, pour the oil and coolant in and hit the start button, with a small detachable temporary fuel tank. If it fires and runs, the rest would be tuning it with a strange permanent grin on my face, which would definitely make people think I've gone crazy, haha
