Quite sure it has nothing to do with EFI.Hi folks - I am looking to decipher the code engraved on the rear cyl. head on a V-Rod engine. Searched and searched and can't find a site that explains it. Anybody know how? Number is *HHHE909166*. I have found that the last H is the Buell plant in Troy,NY. Because this engine is in a Campagna V13R auto/cycle the numbers cannot represent the VIN and don't appear to. All offers taken! Engine assembly part # is 19973-13K.
Best regards - Mark Lane
