GSX600F AJ,speed too high

First of all, good evening together, at my Suzi(GSX600F AJ)/BJ. 2002 the carburetor was cleaned in the ultrasonic bath because I had rust in the tank. I then covered the tank from inside and bought petrol filter and petrol tap. I got a tank filling far. The mashies ran great the short time. Next day they did not jump on (fortunately in front of the door). Then the carburetor went back to the mechanic of my trust, where he lay for several hours in the ultrasonic bath and I buy a new tank and a new petrol filter. I cleaned the petrol tap thoroughly. Now I have the problem that the Suzi starts super and runs great in cold condition. But in warm condition permanently runs at 3000 rpm. When I drive the maschiene super pulls off. It doesn’t swallow either. Can this be done with a synchronization or should it only be due to a adjusting screw on the carburettor? Thank you for your tips your 82er Daimler
