What carb do I have?

[forgiven]

I have a Keihin PWK but right above the bowl it has 26SA2 QKK on it. I couldn't find anything other than KEIHIN on both sides. I am pretty sure this is not the stock carb for the 01 300 but I thought I heard the guy say it was from an 05...could this be? If so what is this carb? I have to order parts for it and need to know what it is.

Thanks

I believe "26SA2 QKK" is some sort of build and date code stamped by Keihin. If it has a round, screw-on top you have a PWK38.
