Hello, I have a LC4 625 SC – my chain is only completely finished by now – so wants to renew the whole tunes now but I have never done anything like this before. Does anyone have a good instruction how to do it best when changing, what you have to consider everything, what torques, etc? Or some tips from people who speak from experience? Would be really great…! What I noticed – when I was last driving, I am at the rear silencer on the inside (below the suspension) There’s now a hole in the damper but can’t recognize a thread or the like – looks like there’s still a disc or something on it (you can see quite clearly because there’s no dirt anymore ) Can someone tell me what belongs there? *g* Exhaust sounds like shit with a hole. Thanks guys! So long greeting!
