Hello together! Actually I thought that this would be a common topic for the old 2V boxers and the gearboxes with “permanent gear damage”, as I was allowed to read here 🙂 Long speech, short meaning… new topic My R 80 GS, year 94, with 90tkm gives from the gearbox funny sounds of itself. Especially with load changes, partly also during acceleration and, at irregular but short distances, in full speed comes a very disgusting screeching from the gearbox. As the ring spirits in the Lord of the Rings movies, to whom that says something… so not nice. Besides, as soon as this squeaking occurs, very unhealthy vibrations (in contrast to the engine bubble relatively high frequency) are transmitted to the whole machine. Does anyone have an idea what that could be? And further: Where I am already there, how much transmission oil eats your thickness? Is that normal that the 800ml should be as good as empty after almost 3000km? Already quite nice happy, isn’t it? Quite apart from the fact that the gearbox is completely dry on the outside, so no dripping sweat or the like?! Many greetings and already a big thank you for your efforts! Martin
