Keihin ASII markings?

[byost]

I have a 2011 300 Six Days with an ASII carburetor I have gotten the jetting lined out but, I have a quick question. The body of the carb is marked "AL1 0 ALP" the Keihin website says it should be marked "S66" Could this be a GG part number or code?

Is it a 36/38mm. Where'd you end up? I have seen a similar print on mine. Thought it was around the seam to the float bowl. Never thought anything of it.
