Peugeot Speedfight 3 AC 50cc VarioTuning

Hi all, I have a Peug. speedfight 3 AC 50cc, and wanted to ask what I have to change at the Vario that I have a faster suit? Something about the weights has to do with that, I know, someone knows the size of the weights of the Speedfight3 AC? And how hard do they have to be? What does it have to do with the clutch springs? What exactly do they do? Do I have to change them? There are strong and soft… but yes I don’t have a plan therefore I ask you with f Reundlicher Greetings Patrick
