Is there a rule re: VIN numbers and Line Bore numbers that there should be no more than 30 numbers between the two?

Thanks!

Absolutely not.

There can be one digit difference, or hundreds. No "Rule".

I know of at least two bikes in the era with identical VINs and Line Bore numbers. I was rare, but not impossible. Just the odds of probability, a result of how the numbers were applied independently during crankcase assembly and final assembly in "batch" production.
