Did you blow the passages out with high pressure compressed air?
At this point I would soak the entire carb in cleaner, and possibly have them ultrasonic cleaned.
It's possible the needles aren't seating properly - I'd replace them at this point. When you have the carbs off and turn them upside-down you should feel the needle seat before the float bottoms on the carb body. If that's not happening they might not be shutting the fuel off completely.

If I try and blow air through the fuel hose and push the bowls up manually it stops the air from coming through. So would that indicate that they are working?
When I set up a funnel as a gas tank, I did notice the gas was leaving the funnel rather quickly. Much too quickly for a bike at idle. I also notice there is a lot of gasoline in the carb and the rubber engine headers. And I think there is gas in the air box because my air filter smelled of gasoline. I'm not sure if this evidence is conclusive or not but it gets me thinking.
