another isuue with carbs

[05Special]

bike is 05, pc pipes, drag ported with coolhead with 19cc domes.. The bike normally rips some ass but I just rebuilt it and am now having problems with the carbs. (stock) I know I have to get rid of them. It has done this for a while now... It will not idle and hesitates when the throttle is whacked from a low rpm..I am having a lot of trouble starting it also.. I have 340 mains, needle in the middle clip and stock 25 pilots..Also I have clamp on filters. Would the small pilot cause all of this? I am going to try a 27.5 and see if it gets better. It has been doing it for a while now and can't figure it out. if i keep the rpms up it runs great and hauls some ass but as soon as i let off the gas it dies right out after coming down to low rpms.... Thanks guys, appreciate the help...

What pipes do you have, where is your timing, and where are your air/idle screws set at?

Sounds like an air leak to me since you say you jus rebuilt it and that it was fine before.
