Any good write ups on jetting and tuneing banshee carbs?

Is there a proper procedure for when you first set up a new combination and don't know where you need to be with the carbs? I just set up stock duals with a fresh rebuild. I started with the air screw out 2 turns out with 25 pilots, 330 mains and clip on middle position. The idle has been acting weird. I've set the idle with the aid of the airflow meter. I'm pulling 4" at idle and its seems a bit to high but if I lower the set screw anymore it will rev down and die out. If I back out the air screw on either one it will die. It doesn't seem to change at all from 1/4 turn in to 2 1/2 turns out. Do you have to move them at the same time to get an accurate reading? I don't remember which way it is if you have to turn more then 3 turns out then you need a bigger pilot or is it the other way around?

Duncan Racing has a great carb write up in their tech section.

Good info, thank you.

It runs better with the air mixture screw closer to closed so I need to go bigger on the pilots. I'm also missing my carb hose between the carbs. I ordered some dealer parts for the carbs and what not.

If the choke hose is missing on the stockies, it will never run right.

I gather that after I read the article. I went directly to the dealer website and gathered up a list of things.

I found a place to get a good run in that's not to far from home. I started with 320 mains. After an hour and 3 jet changes I'm getting closer. The weather started to turn cold. I've got 360 mains in it and I have some brown on the plug. I'll go back when its 80 degrees. Yesterday was only 50. 30-40 degrees will surely effect the jetting.
