Lost air in the front tire - made it home.

[Six7390GT]

So as I always do, I aired up my tires last week before riding the Valk for the first time this season. My first clue should have been the front only had about 13lbs in it before I added air to it. After about 5 miles, as I was taking a left turn the front felt heavy, and just wrong. I pulled over, and that front Avon Cobra was still stiff in the sidewall. I had to assume it was flat again because I sure couldn't squeeze the sidewall, since it was just a 35mph zone  I rode it home like I was riding on ice. It was pretty stressful. It had 13lbs of air in it when I got home.
So I've got a new set of Shinko 890 Touring tires for it, which sure look like the old Cobras, and I'm realizing it's been about 9 years since I've bought the bike, and immediately tore into doing some maintenance on it. I de-smogged it, rebuilt the carbs, rebuilt the brake calipers, polished the wheels, installed braided stainless clutch and brake lines and did the final drive service. I've only got about 5,000 miles on it since then and it's stored indoors on the jack, so I'm planning on just replacing the tires unless I see an issue.  Now I'm realizing I've totally forgot how to correctly pull the wheels for new tires so I've been researching the process. I've got a J&S jack, and I'm remembering that pulling the front wheel is pretty straightforward. I also remember the rear being a pain, especially getting it back in there. I'm pretty sure that I used Dag's video as guidance, but I'm not certain. I've also looked over the articles I found in the tech talk section. However, as well as strapping the bike down to the lift, I seem to recall strapping the swingarm to limit it's travel to avoid damaging the rear drive. Is that necessary? Or was that done when pulling the exhaust to remove the rear? I just can't recall, and I don't want to mess this old beauty up.
So - does anyone have advice, or an article or video that works well for pulling and installing that rear wheel?
Thanks.

Where are you located?  Sounds like you need someone that knows how to help you especially with the rear wheel.

If you are still running OEM valve stems, a failed valve stem on the front could be your problem. Switch to all metal

Yes, it is necessary to limit the travel of the swingarm. You can damage the ujoint if the angle of the driveshaft is too severe.
