Are you just idling and reving the bike without the airbox or riding? riding it w/o the airbox is bad news and will make a big difference. If not, and you are just idling it, don't even bother testing flat spots w/o riding it and getting it to norm temp.

Did messing with the idle screw fix anything?

BTW i have my needles all with the same clip position. Were any holes drilled into your air box to modify it? If so, I would get some epoxy and seal them up.

Returning the bike to stock or getting it close is always a good option.

I would start with the recommended fuel screw settings and test ride/check spark plugs from there to see if any changes need to be made.

Rode it to work and sounded marginal a sputtering but not the major sputtering lurching and gasping Idon't know if it is a miss or what or the best way to describe it or in bike terms that is. if it was a car I would say it sounds like some of the time it isn't running on all cylinders but I have issues moved around bad miss moved up to around 4 k or I call it a miss. It is sputtering some popping on decel. but I don't know how to effectively describe a miss or what a flat spot sounds like.
but after 30 min of riding it really vibrated bad from 4500 to 7k.
I replaced the plugs right before jacking with the carbs so I hope I didn't foul them and thats all.
open to suggestions.

Then we tried to oil and reseat the other 2 and managed to get one of them working as well. just wierd cause they all look the same. i Guesse i should look for a couple of replacement diaphrams for this. any suggestions on where? again thanks i think you saved me alot of head ache.
