frame and engine #s out by two

[trevor saxe-coburg-gotha]

If a bike's frame and engine numbers are out by two digits do they "match"? I ask because I recently spoke to a seller who, when I asked if the bike had matching numbers, said ah well that's a good question and the answer, strictly speaking, is no. He then said he'd asked around and been told by one source that a minor mismatch like this was not unheard of - and that as such, the numbers do 'match'. Me, I don't know. What he's saying makes sense (I mean, what're the odds of blah blah - you get me) - but on the other hand, aren't the two numbers supposed to, well, match? The bike in question is an early '80s Honda.

The main thing is that they match whats stated on the logbook.
