With some bite 8/10, with good bite 10/12 range, with Great bite higher yet.

Air pressure totally depends on amount of bite in the track, but champ karts are usually 2-3 lbs. more air than flat kart adults.
If theres a heavy driver there, and he is on 6-7 lbs., you will more than likely be on say 8-9 lbs.
Of course there are always exceptions but this will be somewhat of a help as a guideline.

Is this because of the weight of the champ? Or does it take the extra pressure to free it up from being less flexible than flat karts?

Requires the added pressure to help free it up.

More weight and more transfer from the higher CG.

Thanks for clearing that up.
