Well, I still think I'd follow Uncle's advice: GO into the DMV and tell 'em you've got a bike that has no title, and was never titled in NC, as far as you know. Turn on the charm, be dressed not like a heroin addict, nor like a used-car salesman, and see what they say...
Maybe even load the bike into truck or trailer and bring it along. IF things look promising, THEN mention that you've got it with you. Here in FL, the tag agency clerks will walk right out into the parking lot and do the VIN Verification thing.
Or, buy a derelict that DOES have a title and either swap frames, or just keep the derelict and get a plate for IT and put the plate on the good one. True, if you get pulled over, the officer MIGHT note the discrepancy, but I'd play those odds. I mean, one 40-year-old Honda registered to you looks very much like another 40-year-old Honda... Of course, you couldn't SELL it, but it'd be a way to semi-legitimately get on the road.
Good luck.
