I have the Dyno Jet kit too. Apparently (acording to a guru I trust), the needle is pretty good but the jets that come with the kit are way too rich. Keep in mind that the Keihin jet numbers are different than the Dyno Jet jet numbers (google it and you should find the crossover chart).
Anyhow, for my setup; stock engine, FMF Q4, no snorkle, L-mod and twin air, he recommended a 142.5 Keihin jet. 2 turns out on the fuel screw. I'm at 1500' elevation.
I'm no jetting expert but the fellow that gave me the specs is. Take it for what its worth.
