You should start from the beginning.
1. Fuel Pressure-Is there enough? My ZX7 use to "kink" the hoses when I put the tank back on. Check for kinks. Also check the fuel filter. (the problem is not too much fuel)
2. Air-check for constriction, you should hear air from the front air intake, not the airbox-kinda sorta.
3. last but not least if anything, fill the carbs up, take the tank off, tank the filters off and run it. you should get a good 15-20 seconds of fuel-rev and see if its a fuel or air problem.
4. your plugs might be too cold. get hotter plugs
Last but not least-take it to a mechanic.
