philcbr Posted May 16, 2017 Report Share Posted May 16, 2017 Hi Can anyone help me with information about the exhaust system on my 1980 RL250? I'm trying to find out if the main box has any sound reducing material inside or is it just an empty box? I have cut open the rear box and found evidence of some sound deadening material, so I will clean it up and re-pack it and weld it up.

philcbr Posted May 17, 2017 Author Report Share Posted May 17, 2017 For those who are interested the inside of a RL250 main box looks like this: http://i513.photobucket.com/albums/t336/philcbr/RL250%20stuff/DSCF2755_zps5mlqwzrg.jpg http://i513.photobucket.com/albums/t336/philcbr/RL250%20stuff/DSCF2759_zps66zpinn7.jpg Gave the inside a quick clean with a wire brush, looks ok. There is something behind the mesh which is hard enough to rattle, I’m guessing it is the remains of some sound absorbent material mixed with the oil which has formed a hard substance. Replacing the wadding? Will be difficult as the mesh is spot welded in place….more work. Phil Quote Link to comment Share on other sites More sharing options...
