Depends on the "kenpo" lineage as well as the "kajukenbo" lineage.
I would wager my Kajukenbo doesn't look much like most kenpo you have seen - on the surface.
Especially since we do not practice "katas" at all.
We mostly train boxing, FMA and grappling instead.
The only "sparring" we do is full-contact JKD kickboxing (16oz boxing gloves and full mouth guard for beginners) or vale tudo rolling.
Occasionally we will do hard contact stick fighting (wearing some protection) or full-contact Predator Armour training.
We do not train for "point sparring" tournaments at all, although some of my Krew do compete in open grappling tournaments, like NAGA.
