Confirmed that the starter solenoid is fine, it's just the button assembly that needs repair. I connected the Yellow/red wire from the solenoid to the battery positive and the engine turned right over. I connected an aux tank to the carbs and with some carb cleaner was able to get it to pop and almost start, but couldn't quite get there. I ended up running the battery down a bit, so when I left I hooked it up to a tender to get topped off before I get back tomorrow night.
I also drained the oil and added a couple quarts of fresh. I have a new filter, but didn't replace it at this time since the header is in the way of easy removal.
I attached the top half of the airbox and got the bleeder screw on the front caliper to loosen without breaking.
The sheet metal screw in the rear caliper turns out to be screwed into a broken bleeder, so a project for this weekend will be to pull the caliper and drill out the bleeder and replace it.
