carb issue.
so i have cleaned the carbs the jets, and triple checked it all. my problem is that it will only idle about 3200 rpms and if i hit the gas too fast it will die or bog down. i just did valve adjustment on it and still same thing, also replaced the float needles and adjusted them to 17mm. i have the stock air box on it and stock exhaust and also new battery. i have messed with the air/fuel mixture and it is set at 2.5 turns. any ideas.................

Are you sure that your diaphragms are undamaged and are responsive to changes of engine vacuum?

ok so i have dipped the carbs and it runs great above 3k but when it goes down to idle just dies, i have messed with the a/f now out 3 1/4 turns and it kind of wants to idle about 2k if i hold the throttle. if i give it any gas it will jump to 4k and then stay there for a min then drop down little at a time to quiting... unless i blip the throttle then it will go up to 4k and back down slow and stall if i dont give it more gas. im going to say that the jets are clean and can see threw them. the ports are clean from what i can tell, i can blow air threw them and when i dripped water in there the jet goes it comes out where it should in the carb im at a loss for whats going on.. help...............

Check that enough fuel is reaching the carbs.
It would be good to check the level inside the bowls.
