So I have yet to investigate what clip position the needle has but the jetting info you gave is exactly what I am running right now.
Some more info that I have on how the bike was running before I pulled the carbs. When ever a lot of throttle was given the bike would bog or if the throttle was bliped the bike would bog down if not die. the bike would run great from about half throttle onward but the bottom end was lacking.
That EXACTLY describes how mine ran after adding new headers. The fix: lower the clip on the jet needle to give maximum richness.
Understand why: from about "1/2 throttle up" the piston raises fully and the needle is all the way up and not restricting or metering flow. The amount of fuel is determined mainly by the size of the main jet.
But, at lighter throttle openings where the piston is only partly raised, the position of the needle with respect to the piston has a HUGE effect on fuel flow.
