Hello, I have the following problem on my Domi: In the 3rd gear the gearbox gives a grinding whistling tone of itself as if the chain were grinding… In all other gears the gearbox sounds normal and switches relatively clean… Achja and there is still a problem and I had controlled the oil level in the cold saddle because I didn’t know that you can only control when the engine was running warm… That’s why I assumed that there was clearly too little oil in the system. i… It was too much now. I then drove about 100 km until I noticed that the machine drips at the bottom of the engine housing… Now my question would be: What can be damaged by the too large amount of oil, which seals and Simmerrings may have to be replaced? Does anyone know advice…? Thanks already in advance…
