Hi I have a r27 with SN 383694 on both engine and frame and its a 1965. That will narrow it down for you a little. Really the last year was 1966 (few 66's got shifted to 67). i'm guessing its a 64

My R27's number is 381128.
It's a 1965 also, but based on the dates and VIN numbers referred to in multiple official BMW Tech Bulletins, I would guess my actual date of manufacture to be 64 or possibly even late 63.
