Hello together, I have a problem with my scooter – Piaggio Vespa ET2 50ccm From a certain speed it starts to squeak quite loudly (see audio) and once it has started, then it doesn’t stop until the engine is off. I also have no idea where the squeak comes from, because it is very loud. Have a new V-belt pure but it doesn’t seem to be that. I thought at first that it somehow slips through or resembles.
