Injectors don't know if they are plugged so I don't think ohms is a good check for that unless it was just dead totally maybe. If it will run, I'd put a strong injector cleaner additive in a drive it for an hour or so. The parts that are gunked up from old gas aren't easy to clean from the injector even out of the bike. It does only open when energized as well. The blockage is more internal at the nozzle where very tiny holes are.
This method is easier too. Drain the tank, clean as best you can and start with fresh gas and inj cleaner.
