Hello
You must have gotten the carbs set up wrong. I assume you used a carburetor synchronizing tool called a "Manometer"? You can either have mercury columns as a balance er or vacuum gauges, make sure the engine is fully warmed up and at the proper idle speed and you have a fan on the carburetors. I suggest you bench sync the carburetors 1st then using the idle mixture screw fine tune them on the engine, they will be very close. Here is the procedure for bench syncing.
To bench sync the carbs. Pull the carbs, run the idle knob all the way in to open up the butterflies. Using a the smooth end of a tiny drill bit as a feeler guage, adjust carbs 1 & 2, than 3 & 4, then make sure the two sets are matched by using the center adj. screw and guaging carbs 2 & 3. Once finished, back the idle adj knob all the way out, and then screw in until you see the butterflies just move. This should set you back to just about correct on idle.
Now more fun Provided the the carbs are bench synced with great precision and patience, there are no vacuum leaks, and you own a carb sync, you can now go back and re-sync the carbs using the idle mixture screws. This will be touchy, as very small variations in the screws will be
needed to get all the carbs mixed evenly. Isolate the sync from vibration by holding it up on something other than the handlebar. Adjust the idle mixture screws ever so slightly to even out any variation that the sync shows. Gently increase rpm, and you should notice the sync rise more evenly than before. And there should be little if any variation in sync levels at 3k rpm. The bike should cruise at 1/8 throttle much smoother now. And all light handed acceleration will be much stronger too. Ideally, an Exhaust Gas Analyzer should be used to do this. The nice type that uses a insert on each header pipe to read CO2 and give perfect stoichiometric air fuel burn ratios is the best way to make sure the carbs are super dialed
If the bike still runs bad after syncing them and you want to rebuild the carbs please go to the web link below for the whole job with picures, very detailed, was posted by an FZR owner.

A bench sync means removing the carbs from the engine, a very easy job on this bike.
I copied this from a technical article I"ve read .

im happy you answered my question but i am a laymen, what do you mean pull the carbs and am i sticking the smooth in of the driil bit in the carbs themselves. do you mean take the carbs off the bike.
