Had my fuel tank off for a few days. Just got repairs (starter switch,
throttle cables) completed tonight. Took the bike for a ride for a couple
miles.
Came home, parked it.
Went back out, and had substantial trouble starting it. But once started,
it was as peppy as ever.
Question: when the tank is disconnected, do air pockets form anywhere in
the fuel system that take some time to work their way out? Any other likely
explanations?

Has it got a vacuum tap? If so, it can take a while to build up a fuel
flow through dry pipes. Sometimes, when a tank's been off a bike with a
vacuum tap for a while, it's quicker to set the tap to 'prime' for
start-up.
Otherwise, no worries.

Make sure you didn't put a kink in the tube from the tank to the
petcock or something. That's a common issue on some other Hondas as
it's hard to work in the cramped space and small tubing.

You've received all the best ones already, but one other
possibility that comes to mind and which hasn't been mentioned:
your bike, I think, may be a little young for this, but if there was
any sort of dirt, debris, or general crud in the tank (which had
been just sitting there harmlessly off in a corner or seam), taking
the tank off and moving it around might have disturbed this such
that a bit got into the fuel later on and caused some momentary
fuel-flow problems. Probably wouldn't hurt to take a look at
your fuel filter if you can do that easily.

Probably your carbs dried. If you have a vacuum operated petcock you'll
need to crank your engine just to make your fuel flow. In this case it
will take quite a time to fill the bowls.
The other possibility is drained fuel pump, if you happen to have one,
though if it drained completely you'll probably ask why your bike didn't
start at all. ;-)

Air pockets generally do not matter.
