dozerash Posted May 8, 2020 Report Share Posted May 8, 2020 Anyone have any suggestions on a aftermarket muffler for my 1980 TL320? Thanks Quote Link to comment Share on other sites More sharing options...
turbohead Posted May 9, 2020 Report Share Posted May 9, 2020 If you don't care about the rather specific look of the OEM part, about any mx silencer will work OK. Quote Link to comment Share on other sites More sharing options...
pschrauber Posted May 9, 2020 Report Share Posted May 9, 2020 (edited) Best thing would be to reopen the existing and refresh the exhaust insulation and the clogged internal hole tube, then do the same with the rear exhaust where you can too replace the inner baffles against a bigger hole tube and insulation (likewise the Jumbo has). Most effect has a redone mid exhaust then the rear. I have done so to my Bultaco, which has the same system of mid and rear units with good effect. I don't need for the SWM, as I have still NOS rear and mid section exhausts as spares...

turbohead Posted May 9, 2020 Report Share Posted May 9, 2020 If interested, please, have a look at one of the older threads here where I have attached some pics of how it's done to keep the "right look" and have a modern working exhaust.

I really like your exhaust set up! The fact you can repack it without having to weld it again is nice. I do have a DC tig I recently picked up (it’s actually a 3 in 1, plasma cutter, dc tig and dc stick welder). I don’t have the Argon tank yet. Not that I couldn’t weld it with my mig, I just think it would look better with tig. I just don’t know if I’ll have time right now to build it like I want. Was hoping to find something to use until I have time to fabricate the old one. What are you guys using for a new perforated tube? Quote Link to comment Share on other sites More sharing options...
pschrauber Posted May 9, 2020 Report Share Posted May 9, 2020 (edited) I buy all that stuff for exhausts here they are specialized one hardware to exhausts, depending the diameter you want from 20 to 100mm they can deliver what you need. I believe it was 38mm, that fittet well for welding ... but I can now mix it up with other bikes... https://www.hild-tuning.de/auspuff-siebrohr/ Edited May 9, 2020 by pschrauber Quote Link to comment Share on other sites More sharing options...

I’ll start looking in the States for exhaust parts. Quote Link to comment Share on other sites More sharing options...
dozerash Posted May 13, 2020 Author Report Share Posted May 13, 2020 I ended up cutting open my stock muffler with my plasma cutter and Dremel tool, worked good. Re tacked all the baffles and welded back up. Didn’t turn out too bad, wish I had a tank of Argon for my tig and done a little neater job. I might go back over it with the tig before I paint. 1 Quote Link to comment Share on other sites More sharing options...

turbohead Posted May 13, 2020 Report Share Posted May 13, 2020 Looks almost OEM, I hope it sound the way it should, too. Good, old fashioned work (no nasty tricks, like mine...). 1 Quote Link to comment Share on other sites More sharing options...

We are only going to the grocery store now, so there is no metal bits to buy ☹️ Quote Link to comment Share on other sites More sharing options...
turbohead Posted May 14, 2020 Report Share Posted May 14, 2020 Living in another country, with another approach to the current situation, it is hard to comprehend the affects of a more or less total lockdown like in the US. No metal bits to buy makes me sad and lonely....... Being a civil servant, I have been working from my home office since mid March and no change in sight. Apart from doing more video-sessions than ever before, it is not that bad (still not infected, of course...). There is also time for a few hours every day in the workshop, right now restoring an old Atlas Copco Cobra rock drilling machine, very odd solutions in there..... learning new thing about old tech every day. And using an old US Army manual as there are almost no documentation on these things left elsewhere. Looking forward to normal biking, soon! 1 Quote Link to comment Share on other sites More sharing options...
