Default GS450 carb problem

I have a 1981 GS 450S. I got it without any carbs. I purchased a set and had them rebuilt completely. The unit will run now, but only at 4000 rpms with the choke (fuel enrichment) on full and stalls when I rev it up. I have checked it and the jets are not plugged. I have had the carbs off many times, but they are clean as a whisle inside and there are no air leaks I can find. Can anyone help??? I would hate to have to junk the bike, it is in excellent condition.
