Lookin for some insite, heres the deal:
new 'used' motor in my zx6r (99 motor) with 5 k miles, dyno jet jet kit, yoshi full exhaust, adjustable ignition advancer; advancer is set to only 2 degrees, jet kit is set at reccomended settings but im getting alot of probs.
From a bit of lean surging at 4-5k rpm, and big probs like flat spots (more like holes) when accelerating hard, the kind that will drop me from 2nd in to netural. Just replaced the fuel filter, and plugs, but cant seem to aleviate the problem, any ideas?

I'd say your carb settings are off.
My 9 had the same prob stock. They were known for that.
I installed a Factory Pro jet kit with great results.
They include replacement emulsion tubes which makes a big difference in getting rid off flat spots.
You first need to verify that your main jets are of the correct size. Then make sure the needle is correct, then the pilot/ mixture screws.

i know that i can fix the low rpm surging by raising and lowering the needel hights, but the major holes deffinatly dont seem like carb problems. mixture screws were set, and carbs were sincronized by a shop, main jets i used were the reccomended ones, im just concerned that the motor i put in has problems, bought it from fast lane, only other concern is that this might a sign of the fuel pump starting to go. i have no idea how long the motor sat, put new oil, oil pickup, and filter on the motor when i got it, and have since installing it only put bout 50 miles on it, dont really know if i want to mess with it anymore, might just take it to fairfax cycles.

Let me try again.
ZX's are known for flat spots in the powerband.
Hence the replacement emulsion tubes in the Factory kit.
You can change needles all day and it won't help.
I'd also remove the ignition advancer to see if that changes things.
Maybe there is something else wrong but I'd do that first.
Of you can not mess with it and pay alot of money for someone else to check it for you.

A jet kit for the 6r dosent replace the emulsion tubes, you get needles and main jets. Advancer was set to zero degrees, but i plan on adjusting the mixture screws, and playing with the needle height, as the high rpm problem was fixed. i feel really stupid about what was wrong too. after replacing the motor i hadnt put most of the body work back on as well as the tubes leading to the air box from the ram air ducts. zed's have small tubes inside the ram air ducts that equalize the pressure around the float bowls in the carbs. because i left off part of the ram air system it was creating a vaccum around the float bowls and cutting off the fule supply. re-install the tubes and its all fixed, now just a little tuning for optimum power and torque curves.
thank god, im on the road again bike in good running order for the first time since the motor went on 211
