Any other suggestions on a jet kit to try that works.

Cheap Chinese jets with questionable size markings on them. No needle, just some washers to shim it up. Not much of a value for $50.

The stumbling just off closed throttle can be blamed on the DynoJet recommendation of running the mixture screw at 2-1/2 turns out. That will be way to rich and cause a rich bog just off idle. Most riders have had good results by setting the idle mixture right on the lean edge of the smooth idle range - usually around 1-1/4 turns out.
