Hi, I have a BMW C400X and I feel a vibration from the clutch when I accelerate gently, only at low RPM. It feels like the clutch is slipping. The same thing happens when I slow down and the clutch disengages while the bike is still moving: if I accelerate again, I hear the same vibration and a noise that sounds like a faint squeal. Once the clutch fully engages, I don't hear anything. Do you know what it could be? The CVT belt and rollers were replaced recently, but I didn't do the work myself.
