Speedfight 3 LC F1ABAA overruns.

Hello to all I hope you can help me and that I have the problem that starts at 45kmh the scooter to overturn goes dan to 10k turns. I have the throttle disc on the Vario on it. It is a Sport Pot of sito on it but is throttled. I tried it with heavier weights already brings unfortunately nothing in again have 8g in it. The only thing I still have is the throttle where I can still build it but then it doesn’t have the power. Thank you in advance Greeting Andrej
