In my experience “binding” is related more to mid-corner speed than to entry speed.  My guess is that you are entering the corner, getting axle hop and lifting, and then finding that your exist speed sucks.  Concentrate very hard on maintaing speed after entry, getting on the throttle early and keeping the kart right on the edge of the traction circle.

Also, I’ve had some success decreasing the air pressure in the outside rear tire (drivers left for counterclockwise circuits, right for clockwise) by as little as ¼ psi.  Check your pressure immediately after your next run.  If the outside rear tire pressure is higher than the inside, reduce the psi to make it more even.  I started doing this when I noticed that my axle binding problem was much more pronounced on turns corresponding to the track direction.
