I had the air cleaner off warming the bike up to do a shock treatment. Looking into the carb with the bike idling I could see dropplets forming on the butterfly that looked like water. I had seafoam in the gas so I don't know if it was water from the humidity or sea foam forming on the butterfly. Has anyone else seen anything like this before?

Yep, this happens with most carburetors when the humidity is high.
The venturi-effect of a carburetor causes a slight refridgeration effect and this cools the carb parts causing the warm moist air to condense moisture on the throttle plates.
Sometimes in Chevy's old TBI fuel injection, you can look at the throttle plates and see what appears to be tiny droplets of gasoline dancing all over, looks like water but it's not.
