Dripping from the carbs

My bike is running great thanks to many suggestions here (re-jetting etc)

Here is a weird thing: As soon as I shut down the bike, gas will drip out of the 'over flow' tubes from the carb bowls.

I must quickly shut the petcock to prevent this.

Whats up with that?

It may also be dirt or wear in the float needles, so a good sort out of everything would be in order. I had one where I was mystified by a leak until I discovered the overflow itself (the brass tube that comes all the way up from the bowl)had a hairline crack in it.

Cracks in the overflow tubes can be almost invisible, look closely.

Does it leak at all when she's running? I'd try tightening up the drain screws, had that happen once, didn't have them tightened up all the way, and she leaked when I shut her off, then the next day she was completely dumping gas everywhere while I was riding, went through 4 gallons in 40 miles, and that was the float needle needing to be cleaned... Since it's when she's shut off, that makes me think it'd be the drain screws or a cracked overflow tube
