Good test! A bucket slowly poured in will *not* under any
circumstances cause self-siphoning of the trap.
(Anyway, the old toilet didn't self-siphon.)

So......that leaves a defect in the bowl. Doesn't happen
very often and I'm sure the factory tests for it, but there is
apparently a tiny hole in the clay between sections of
the internal trap. This won't leak outside the bowl,
but permits the trap water to enter the drain.

Document what tests you did and ask how to return it.

Just installed a new Kohler Cimarron toilet in a rennovated bathroom.
When I flush it seems as though both the tank and bowl fill but then
once the tank is done and shuts off the bowl starts to drain and I
hear water trickling until the bowl is almost empty.
Anyone able to offer a suggestion as to what's happening?

thanks

If all (or almost all) of the water drains out, there may be a
crack/flaw in the bowl and the water is just leaking out. Slowly pour
water in the bowl until a normal water level is attained. If the water
level drops, there is a problem with the bowl. If the water level stays
the same then you have a vent problem.
