The answer to your question is "none."
But the jets and the shims (washers) without a kit. It's not like the kit has any advantages whatsoever.

The reason jetkits costs more is not the jets, but the needles. They are identical needles (at least newgen) and have a different taper to them vs stock. Removing the airbox also requires more fuel which means larger jets.
