1990 FZR1000 carb problem?

My bike has a full exhaust and open airbox. So I have a set of carbs for a 90 FZR1000 with a stage 3 dynojet jets. Basically i replaced my "stock" 1990 carbs that run rough and die at 5500 rpm with these 1993 FZR1000 stage three. The guy i got them from said they were cleaned and sync. I put them on my bike and it sounds as if it's running on 3 cylinders. Also the carbs on the right spit out gas when you open the throttle and they run hot! As you touch the diaphragm plastic cover it's much hotter then the two left ones. I sputters and idles like crap, it wont stay alive even adjusting the idle. The RPM fluctuates. I placed the old Stock carbs back on and it runs fine (up until 5500 rpm as it did before). So what it the problem? Thanks for the help
