If that frame number is correct why's it got a K0 number beginning with 1 when it should be beginning with a 2 if it's a K1?

I have no idea - Bryan might know the answer - it's not the original alloy plate as is obviousy been hand engraved from a blank to match the headstock stamping.
The headstock stamped frame number it's the same as the V5 1030*** first regd 23-3-1972. So what does it being a KO change assuming you are correct?
The engine number starts with a 2 - I was advised it was not the original engine by Bryan.
Oddjob:
AFAIK the K1 had the frames and engine numbers starting with a 2 not a 1 which was how you could tell from the K0 version. It's possible it's had a new frame fitted at some point OR it could have had a K0 frame fitted by the factory but I'm doubtful about that, the frames were essentially the same so it's not a big issue, just a curiosity. Have you checked the frame itself for the stamped number on the headstock? to make sure they match.
Bryanj:
Ken, the frame and V5 came to me in a "job lot" from either London or Liverpool, cant remember which as i did a grand tour collecting bikes and bits after putting an add in Classic Bike for parts wanted and getting a few answers. Absolutely no chance of remembering where from as it was before i got together with my now wife and weve been together over 20 years.
I engraved and fitted the vin plate as the stampings were not that "heavy" and i reckoned they would be damn near invisible whe$ powdered. I thought the 1 was K0 and 1 and the 2 was K2, which we never officialy got but Honda carried on the numerical order by year, i will look in my id book, which admitedley is US and post a pic of the page later.

The stamped headstock frame number matches the V5.

The V5 only reflects the numbers someone informed DVLA of. If you inform DVLA of an engine or frame change, they change the numbers on the system and the V5 is changed to reflect that. It doesn't mean the engine and/or frame numbers are the originals they left the factory with.
Edit.. I should have said does it really matter in your case anyway Ted? Its not as if you are restoring a bike to standard spec or concours. My Mongrel build Millie is a 550 K3 frame with an 550 F2 engine and I don't loose any sleep over it. If it were a miss matched pair on one of my 'proper bikes' then I would worry 😁😁😁
