After a hard fall my 1998 CBR 600 F3 floods to the point of raw fuel dripping from the headers after 3 or 4 cranks. Anyone have any ideas of what is wrong?

I had a '93 that did this, gas just flooded out. If I remember correctly, one of th floats had stuck open.

That day was basically the end of my CBR, but not for that reason. I parked it off to the side and walked a mile back to my dad-in-law's house to get some tools. While walking there and back, someone managed to back into my bike and knock it over the curb to the sidewalk 3 feet below. Never ran right after that.

smack the bottoms of the carbs with the _handle_ of a hammer, sometimes that frees the stuck float valve.
Then take the plugs out to let the cylinders dry out.

The inlet needle on one or more carbs is stuck open, which can be from dirt or maladjusted floats. If it started this behavior after a hard fall, the needles may return to normal once you get them unstuck. I agree with tapping on the fuel bowls with a hammer handle, just don't go caveman on them. If they don't re-seat, take the bowls off and figure out what's wrong.
