Wouldn't spraying some carb cleaner in there accomplish the same thing??? At least carb cleaner is combustible.
Water expands at about 1600 to one when it turns into steam inside the combustion chamber. It's this expansion that will remove the carbon over something like carb cleaner that would just combust like gasoline.
so if I was to use a spray bottle on mist setting , even if it didn;t help the the occasional misfire I'm getting , it really would not hurt any thing and may actually help by removing some of the built up carbon in the bike . You guys are like Harley mechanic dictionaries .
It wouldn't hurt a thing.
