brownie001 Posted December 28, 2019 Report Share Posted December 28, 2019 Hi, I'm trying to get hold of an exhaust silencer for my Cota 247. In the attached picture it can be seen top right. I've tried most of the usual sources but have had no luck so far. Thanks in advance, Phil Quote Link to comment Share on other sites More sharing options...
cleanorbust Posted December 28, 2019 Report Share Posted December 28, 2019 These occasionally come up second-hand on eBay. You can get a WES replacement, I think In Motion Trials do them, but a much lower cost alternative is a Volkswagen Beetle tailpipe, again on eBay for about a tenner. It's a direct fit on the exhaust pipe and easy to make a bracket to secure to the silencer mounting on the frame. This was a well known mod back in the day, even the works riders used them.

cleanorbust Posted December 28, 2019 Report Share Posted December 28, 2019 Rob Edwards' works bike with VW tailpipe. If it was good enough for him... Note also rear suspension units top mounts repositioned further forward. 1 Quote Link to comment Share on other sites More sharing options...

brownie001 Posted December 29, 2019 Author Report Share Posted December 29, 2019 No disrespect intended Keychange but if you've found something, please supply the Link. The search results vary depending on what part of the world you're in. Sammy Miller was taken over, all products can now be found at Feked.com I looked there first and found nothing compatible.

This parts pic is really old, maybe '70 or '71, I don't really know. It's gunna be annoyingly loud with that type of silencer. Quote Link to comment Share on other sites More sharing options...

Meant to say, I don't find the exhaust note on mine with the VW tailpipe to be much different from standard (I still have the original silencer which I removed), and I'm not a fan of loud bikes. The mid-section silencer does a pretty good job. Quote Link to comment Share on other sites More sharing options...
brownie001 Posted December 29, 2019 Author Report Share Posted December 29, 2019 70 to 74 MK4's and MK4B's had them fitted but it's the chassis numbers which are important. 21M6600 to 21M6699 Quote Link to comment Share on other sites More sharing options...
cleanorbust Posted December 29, 2019 Report Share Posted December 29, 2019 (edited) Mine's a '79. Has the mid section box as in the diagram but it's a welded up one piece system up the point where the back box fits. The pipe at that point looks narrower in the diagram but would be easy enough to make a spacer/sleeve to fit the tailpipe.
