Moinsen!!! Just wanted to ask if the valve is dangerous for the engine or other parts. Nervig is that definitely but it would calm me if someone confirmed that this is completely safe. Just bought me a GL Europe ran 110000 KM and is a 93 year old. Engine looks very good and sounds really good at high speed (1.6 L, 75 HP). Also otherwise it runs “round”. Would be nice if you helped me further greeting Sergio
