You have a dynamic problem-Keith would not have seen that on the static dyno.
Scooter has it exactly right: "It was flooding in corners. So I keep lowering the floats till it stopped, but that ended up being a way to low.' Don't touch the floats other than the way Keith had them.
The cure is not jet extensions but rather vent whistles. They prevent fuel from sloshing into the vent passages in the main body and drowning the the carb(s).
They're cheap and easy to install once the bowls are off. Having an effective cold air system sealed to the hood will cure the problem totally.
If you do nothing just be ready to clutch in and blip throttle while stopping/turning.
