Hello, I have the Peugeot Kisbee 50 4T and bought me the Polini clutch Speed Clutch 3G For Race 107mm for this the right bell from Polini. Now my problem: When starting the scooter is totally slow and does not come out of the quark and the acceleration is really bad. I tried it out with the toughest springs and with those that were already in the clutch. (No success). The wedge belt is also still in order and does not slip through. It would be nice if someone would give me the Peugeot Kisbee 50 4T. can help. Greetings to Jonas
