The Lynx manifold restricts above 6000rpm & gives a little bit more grunt around 3000rpm. I could not work out how to jet one econimically & but I never had a problem with jetting proper dual DCOE's. The bendy parts in the manifold are very big, so they likely do flow OK, just not in an efficent way.

If you are putting Mikunis on the Lynx manifold, you would want small ones. The size DCOE you pick would be smaller than what you would pick for duals. (because it is a 360° manifold)

I'd nearly always use 2x HIF6 or 2x 45/48mm DCOE's

I had a car running well for ages with K-Jet, but I would not take that away from running locally because the bits are all one of. I have a couple of complete K-Jet system from a B21E, but the parts are all similar but different....
