martyq8 Posted September 22, 2010 Report Share Posted September 22, 2010 Hi all, Could anyone tell me should there be some sort of seal/rubber betwwen the rear exhaust section and the middle silencer on a 78 Sherpa. If not what stops gasses leaking from that joint. My bike leaks from there but because I am out of country I havent had a chance to strip it yet. It would be handy to know so I can order parts ready for when i get home. Cheers Marty Quote Link to comment Share on other sites More sharing options...
woody Posted September 22, 2010 Report Share Posted September 22, 2010 They have an O ring on the middle silencer where it fits inside the rear silencer. This has normally perished and the flange on the rear box can get distorted and the end flares out so it is no longer a tight fit. Just make sure the joint is a tight fit and use silicon sealer, regardless of whether you use an O ring again. They also have a spring to hold the joints together, you will see the spring mounts for where it goes if the spring is missing. Quote Link to comment Share on other sites More sharing options...
