'80-'83 GS750 16V Fours with Mikuni BS32 CV Slide Carbs

This is the second gen GS750 with the BS32 CV slide carbs and the first generation of the 16 valve engines. 

 Starting in '71 Suzuki started year coding bikes in the last letter used in the name. You may see this code on your bikes paperwork or in a parts list or catalog.  I leave this off as it is redundant if you are showing the year anyway. There is a chart below to find your year code.

Below is a set of '80-'81 GS750 45400 carbs and '82-'83 GS750 45420 carbs (Not '83 GS750E/ES).  Both sets are shown because all '80-'81 sets have a different choke cable mount than the '82-'83 models. These parts can be switched out to make them work on a different year so they can be mixed-up, but you need to have the right choke cable mount for your bike as it can be very involved to adapt the different cables to the bike itself.
