True. It's too bad there wasn't a way to blow it all out without dismounting the carbs.
But on the other hand not much of what is in the passages is exposed to air and I don't remember it ever causing me any problems, even on the rare occasions I've left a bike in storage for a couple of years.
Yeah, but don't miss the fact that draining or "running dry", if there is such a thing, neither will remove the fuel that sticks in the circuits due to capillary action.
