My VIN is EL401607 ... an early production 1940 EL. I have a couple of cylinders with date codes of 19 - 9, and 21 - 9. I assume these are 1939 codes, but don't know what the two digits before the dash represent. Are these month and day, or something else. I'm trying to determine if these are compatible with my engine production date.
A related question I'll ask here, rather than on a separate thread is when did production typically begin for a model year (recognizing that it may have changed over time, or even from year to year)? Further, what kind of lead time would there be between the manufacture of significant components (e.g., heads, jugs, transmissions, fly-wheels, etc.) and the motorcycle assembly. I am relatively new to old Harleys, and come from more of a Corvette restoration background where all of this info is readily available ... so I recognize that I may be asking questions without answers, or the answer may not make a difference with these bikes.
Thanks.
