Hello together, with my scooter Peugeot Kisbee 2T I noticed that the tank needle falls completely downwards in the stand and at low speeds. If I give or drive a little gas in the stand, the tank needle goes up again. The whole thing happens even when the tank is completely full. The whole looks like this: – I start with a little gas and the needle goes to full within a few seconds (if the tank is half full) – I sit on the scooter and make me sta rtklar, without gas to operate and the tank needle goes about at the same speed again to completely empty, as it went up before – I go off and the tank needle goes up again at the same speed Sometimes you can see that it “shakes” with about 3 Hz within a few millimetres.What can this be and how can you fix it?
