'81 CB750K DOHC Hesitating, Stumped!

When we were tearing apart my broken 750, the rotor was on there pretty darned good.
Your friend here is some PB Blaster, and the little rotor puller tool.  Luckily, the Harley guy who was doing the work had something similar in metric threads, and some wrench pressure and a few taps with a hammer got it done.

It's also easier if the engine is still in the chassis, and the drivetrain/rear wheel is attached.  Keeps the engine from spinning when getting the center bolt out.

Now that I've gotten over spending a lot of money, I'm really excited to get that new rotor installed. I've been tinkering all winter and there is finally and end in site.

I plan on soaking the old rotor in plenty of BP Blaster for a while. Can I just douse the whole thing front and back? Or are there some delicate parts to mind?

I watched those videos that rich posted (thanks BTW), and I feel pretty confident about the process. Thanks to all of you actually, for responding so quickly and being so patient. This forum is such a great resource.
