gpz 900r running probs

[tony b]

ive just got my gpz 900r ready for MOT,but for some reason it wont run now ,i have replaced the tap rubberes and diaphram,as that was leaking ,and ive cleaned the carbs ,top and bottom,if i prime the carbs then remove the tank it will run until the fuel has been used up,but if i try to run the bike with the tank connected it seems as if it flooding,then refuses to start unless i prime it up again then remove the tank,its fitted with those after market air filters but was like this when igot it ,and it ran fine,please help coz im out of ideas now.
