GPZ 600 does not run

Hello together! I’m new here and need help! I recently bought a Kawa and now have the problem that she only starts badly with choke and then runs on about 5000 tours (doesn’t take up to no gas at all). She also has false ignitions as if she is too lean or with the ignition what’s wrong. If you take out the choke then die of the motor, (speed can only be regulated a little over the choke).If you “underruled” her she runs very restless (like a 2 cylinder) u nd “rapelt und klappert” Have already looked around here in the forum and have cleaned the carburetor for K.wasser in sprit, carburetor mixed screws on factory setting (2.0 revolutions out) cleaned candles (have very white combustion image), ignition cable and plug checked (3 are new) Can anyone help me? PLEASE !?!
