Hello, I am new to this forum. A week ago I became the owner of a bmw c600 sport and I am honestly very impressed with the holding and acceleration and the highline equipment. However, the problem arose after a few days of driving and the clutch squeaked while moving and heard an unpleasant sound and slipping. The scooter has 10,500km. I took everything off completely and saw that the clutch pads were bright, I took the paper and tore them down and I saw on the clutch bell that it was already lightly sanded. I sanded the pads again to the light material and the bell, I washed everything and cleaned it, installed a small variomat in the hope that it would now be all right. It was and was in the office literally one day after 20 movements again the same problem appeared. I don't know how to solve the situation and what to do about the clutch, is the only thing that bothers me. The belt was originally installed in the BMW service 500 km ago, as well as everything else in terms of axle seal and more. I read a lot on the internet but I can't find a solution to the problem. Thank you bimmer's.
