I am looking for some insight in what you guys are jetting your carbs to, i am gonna be running the factory twins on my 600 mod but got rid of the tmx's and installing rack carbs, i ride anywhere from 10-30 degrees, how much different is the jetting from the tmx's?

Somewhere between 400 and 440 mains. 800 needles from a summit are adjustable which is nice vs. shimming.
