not a 400 but maybe someone can help?

my zxr750 l1, having some problems with running at the minute since starting to get serious on the whole refresh front. so completely rewired the bike all new bulbs, relays and fuses, checked valve clearances, zx10r throttle tube, balanced carbs and given it a full service including leads, caps and new coils. now the fun part it will run on choke fine and idle for 30 seconds or so without then if you touch the throttle it bogs and if i give it a fist full it wont rev out over 5k. fresh fuel, new fuel filter and replaced fuel tap seals. it sounds like a starvation problem but no fuel lines are being pinched or twisted i have noticed the inner breather on the tank is nakered as the breather was blocked but this caused no issues before hand, pump is operating as it should as is the pump relay, this weekend i'm going to strip, clean and make sure the carbs are set up correctly anyone have any ideas where else to try if this is unsuccessful?
could this be an electrical fault with maybe the cdi unit? i'm at a loss to be honest after 4 full weekends on it now even the 750 nuts can't really seem to point me in the correct direction although it seems a common find on this era of kawasakis. did not have this problem before fitting all of the above bike ran faultlessly apart from having no lights.
