PiP, that's exactly my point. The needles SHOULD keep it from flooding but they don't. Steve's overflow tubes keep your bike from hydrolocking, which is good but it doesn't solve the problem.Hey, I'm always open to a better mouse trap. Let me know when you make one!!

I've done a about a couple hundred sets of carbs now, and I don't agree with cholla's assessment of the needle seat. Now the needles, there is an issue there. The stock needles have very soft springs in them,and as they age they're overcome by the float pressure and start letting the fuel levels gradually slip upwards. Additionally, they have issues with ethanol attacking the bodies and deforming the tips. I use aftermarket needles with stainless steel bodies and much stiffer springs. Not saying they'll last forever, but they certainly control fuel levels better and more consistently. Steve
Steve, have you ever figured out what the cracking pressure is to unseat needles and cause failure in the float system.Would probably be different pressure depending on if the bike was on the sidestand or the centerstand, due to how the gas in the carbs pushes against the floats. (Less pressure when on the sidestand)
Bent rod-small problem.
Gas on floor fumes reach water heater/whatever, blown house. HUGE problem. I used K&L needles after polishing the seats (a jeweler polished them) and they refused to seal. New Kaw needles and they sealed perfectly. Too bad they cost 4x the price of the K&L units.

Not to get TOO bogged down in this, what happens to the gas that is leaking once the cylinder fills up? Hint. It flows into the air filter housing, where it will leak onto the floor.OMG Steve you are so right. Good thing Cholla pointed this out to us.
