Anyone have any idea what this carb is?

I got this single carb in a tote of stuff that came with a couple bikes I purchased. Anyone have any idea what is? All I know is it says Mikuni and has some numbers on the side, tried looking it up and came up dry...

Looks like 2005-ish BSR33 from a Yam Rhino 450 quad
