Servus, I have a question about the adjustment of the flaps in my MJC exhaust? After the winter season I noticed a clapping on the right pot. First I thought the right exhaust flap would be torn down, but if I put a louder direction with the hand adjustment, the clapping is gone! At the weekend I had removed the right pot and found that the flap did not loosen. It should be by the setting! I have now solved all the trains and versuc with me is now at a quiet position, the right train is end-strung without clapping, the left train/pot is on tension and open. Naturally well so, only the rotary handle wanders back to loud again by itself through the tension………. Since I have to go to the TÜV this month, I would need the exact instruction to adjust the trains I don’t blink it thanks Gruss Thomas
