Just a slight bit of progress. I put the bike back down on the wheel chalk and drained the oil. I tried to get the chain off, but was unable. I'll reference the shop manual today on how to do that, and of course how to pull the motor.
At first, I was a little intimidated at the thought of pulling the motor, but I now feel confident I can do it without assistance (once I get the chain off). I told Emily I'd be spending tonight in the garage, so hopefully I'll be able to get it done.
Today, on my lunch, I'm picking up an angle grinder, some cutting discs, and some sanding/polishing/cleaning supplies.
