Variety rollers in the Peugeot Speedfight 3 LC (unset / A1)

Hello, I’ve been with my Peugeot Speedfight 3 LC for a little longer now. According to the vehicle license, this has 4.1kW and a top speed of approx. 70-75 km/h is therefore completely reduced. It is not tuned. However, I would like to change the belt and the Variomatic rollers. Now the question is which weight is most optimal. The scooter has its maximum power at approx. 7,300 rpm. Unfortunately, I don’t know what is currently installed for rollers, which is why I can’t take a reference. Now to the actual question, someone might know which Variomatik weight is best. I have to say that I have to overcome height differences of up to 400m. Lg
