Mikuni Carb ID

[GS_Jay]

I have a set of aftermarket mikuni carbs on my 1100E. I've been trying to figure out what model they are since getting the bike. It's beginning to spit and sputter so they're probably due for a good cleaning and rebuild. Any help would be greatly appreciated.

Those are 33mm smoothbores.

Thanks bro. I'm not that familiar with the older mikuni carbs, just the CV's, the RS's and the HSR's. Are these any good?? Googled them and came up with mixed reviews. My 1100E is pretty stock minus the carbs, 4-1 V&H pipe and pods. Not sure what the jetting is as I haven't opened the carbs yet. It runs ok up to about 3/4 throttle, after that it falls on it's face and sputters out.
