kingy409 Posted June 17, 2013 Report Share Posted June 17, 2013 Hi everybody, Ive just bought a 2001 321 txt and need to ask you guys for some info. Does the silencer connect to the mid box with a seperate connector/sleeve? mine has a connector that fits inside the silencer but it is very sloppy and leaks badly. I would have thought that this should be one piece but i cannot see that it was ever welded to the silencer. could anyone shed some light as to how this goes together please. Thanks in advance Quote Link to comment Share on other sites More sharing options...
wobblenorbed Posted June 17, 2013 Report Share Posted June 17, 2013 Not one hundred percent sure but I think that their should be some rubber O rings in there to seal things up. Quote Link to comment Share on other sites More sharing options...
kingy409 Posted June 17, 2013 Author Report Share Posted June 17, 2013 Hi yes the connector has two red Orings that seal upto the midbox but the other end just sits in a oval hole in the silencer at a angle to fill the hole but it is loose.

dadof2 Posted June 17, 2013 Report Share Posted June 17, 2013 Slap some Dow Corning 861 or similar high temp sealant in. Cheers 1 Quote Link to comment Share on other sites More sharing options...
totty79 Posted June 18, 2013 Report Share Posted June 18, 2013 Mine has sealant, but I've got no idea if that's standard or a bodge. Quote Link to comment Share on other sites More sharing options...
bilks Posted June 18, 2013 Report Share Posted June 18, 2013 (edited) This is a pic from parts book,i know my 321 silencer was same as pic,just slotted of the middle box with the 2 o rings Edited June 18, 2013 by bilks Quote Link to comment Share on other sites More sharing options...
kingy409 Posted June 18, 2013 Author Report Share Posted June 18, 2013 thanks guys, i suppose if i bolt it in place and the go round with sort of sealant it will sort it out. i just wondered if this was how they all are or wether i was lucky and had just got a "special edition" ! heres the pics anyways.

zippy Posted June 18, 2013 Report Share Posted June 18, 2013 looks to me as though it should have been welded in place. the hole it sits in looks like it has a ridge of weld there. Maybe figure out how far it needs to stick out of the silencer and get it welded up. A decent Ally welder should be able to do it pretty quick and easy. Would help the welder out a bunch if you cleaned up as much oil, grease, etc.. off the surfaces as you can. Just a thought. Quote Link to comment Share on other sites More sharing options...
copemech Posted June 19, 2013 Report Share Posted June 19, 2013 (edited) That seems a cheezy cold weld that has separated! For proper fitment, unless you can match up the old weld perfectly, you fill need to take the whole bike to the welding shop for a tack-up and proper positioning. All that must be clean prior, real clean@! Edited June 19, 2013 by copemech Quote Link to comment Share on other sites More sharing options...
thats_a_five Posted June 20, 2013 Report Share Posted June 20, 2013 The middle section and the silencer section are assembled to each other in a slip fit. If you look inside the tube, you can see 2 grooves for O-rings. There should be red O-rings (usually high temperature compound, not cheap black O-rings) in each of those grooves. You can also seal the joint with some high temp silicone seal. Looking at the pics, I see 2 problems. 1) the tube needs to be welded to the housing. 2) the mounting tab has a crack that also needs to be welded. Find a good welder, take the bike there so the parts can be aligned correctly for welding. Quote Link to comment Share on other sites More sharing options...
