I'd certainly try draining the carbs first. There is a drain screw on each carb float bowl. If you drain it into a clean container, you can see if there is any water or dirt present.
The fuel system cleaners and driers will work on bikes as well. Just follow the mixing directions. You just would use less per tank than for a car or truck.
If there is enough water in the carbs to act as you describe, you would still need to drain them first, and then use the fuel additive to clear out the rest.
