Welcome, and congratulations on getting your bike running.

If the bike's been sitting for a while, the air bubble diagnosis is possible.  The SOHC units use a dry sump system, which runs a bit differently than the DOHC's wet sump system.  Priming would have helped, but in this case I think you're OK.  IF it were low on oil and oil pressure for a long while, I would expect lots of dry knocking rattling noises in the engine, which could be catastrophic.  If yours was running relatively quietly for 5 minutes, and the pressure stabilized at about 60 psi, you're good.

Other SOHC riders, feel free to chime in.  My experience with the SOHC motor pales in comparison.
