italianstallion Posted December 18, 2015 Report Share Posted December 18, 2015 Hi all, Just wondering if someone can give me some advice regarding fitting a new S3 titanium exhaust to my Rev3. I have literally just done the install and thought everything had gone to plan. I removed the old front pipe without issue, ordered a new exhaust gasket for the front end of the Ti pipe, ordered two new O-Rings for the centre-box end (all from Lampkins). I cleaned everything up and installed the new O-Rings, inserted the pipe to the centre-box, added the gasket and torqued everything up. When I started the bike up, it was evident that the exhaust was blowing at the centre-box section where the S3 exhaust feeds in. On closer inspection it was obvious that the fit of the pipe was not as close as that of the original pipe. When i put the vernier calipers across both pipes I could see that the Ti pipe is approx 0.5mm down on diameter relative to the original. Has anyone else come across this? Am i missing something obvious? I cant imagine that just adding a load of gum type sealer will fix it. I'm starting to think i need to source different sized O-Rings to suit but what is everyone else doing? I select O-Rings daily in my job but i cant see why i should need to do this? New standard ORings installed to centre-box Centre-box section removed Any help much appreciated! Regards, Stew Quote Link to comment Share on other sites More sharing options...
huski Posted December 18, 2015 Report Share Posted December 18, 2015 High temp silicone will do it,sounds like a bodge but they don't always seal without Quote Link to comment Share on other sites More sharing options...
lockie28 Posted December 18, 2015 Report Share Posted December 18, 2015 High temperature silicone is they way buddy, I take it the orings are the correct fitting? Plenty of silicone and the job will be a good un Quote Link to comment Share on other sites More sharing options...
italianstallion Posted December 18, 2015 Author Report Share Posted December 18, 2015 Ok, thanks for the responses. Found some flexibile Loctite at Halfords good for 350 degC, I'll give that a try! Quote Link to comment Share on other sites More sharing options...
worldtrialchamp Posted December 19, 2015 Report Share Posted December 19, 2015 ..might be a reason for it eg expansion of titanium vs steel. ...not sure..you could ask S3 for an explanation. Quote Link to comment Share on other sites More sharing options...
steve_earle Posted December 19, 2015 Report Share Posted December 19, 2015 Silicone does work most of the time, Or this is a handy tool to expand it and good for reachable dents. I don't think people normally spend that much on rev 3's anymore so you might find only a few have the s3 pipes. http://www.ebay.co.uk/itm/like/272003959542?adgroupid=13585920426&hlpht=true&hlpv=2&rlsatarget=aud-133395220626%3Apla-131843259666&adtype=pla&ff3=1&lpid=122&poi=&ul_noapp=true&limghlpsr=true&ff19=0&device=c&chn=ps&campaignid=207297426&crdt=0&ff12=67&ff11=ICEP3.0.0-L&ff14=122&viphx=1&ops=true&ff13=80 Quote Link to comment Share on other sites More sharing options...
worldtrialchamp Posted December 19, 2015 Report Share Posted December 19, 2015 actually now that I think of it, I recall seeing an advertisement years ago for these S3 pipes and I noticed the Rev3 had a sleeve there. ..let me see if I can find that pic Quote Link to comment Share on other sites More sharing options...
worldtrialchamp Posted December 19, 2015 Report Share Posted December 19, 2015 that's straight out of the S3 Catalogue. Is yours the same? Quote Link to comment Share on other sites More sharing options...
italianstallion Posted December 19, 2015 Author Report Share Posted December 19, 2015 Well it looks the same, all I can compare to is the pic I posted at the top. The dia is around 0.5 to 0.7 undersized compared to original (after measuring a few more times). I can't see that giving you enough annular thickness for a sleeve? The 125 version definitely has an adaptor/compression part. I bought from Gas Gas so I assumed it would all be there? Quote Link to comment Share on other sites More sharing options...

italianstallion Posted December 19, 2015 Author Report Share Posted December 19, 2015 So apparently the S3 pipe needs different orings according to my local trials dealer. Not sure why S3/gasgas do not supply this with the pipe. Pretty ***** if that is the case hmmm Quote Link to comment Share on other sites More sharing options...
worldtrialchamp Posted December 19, 2015 Report Share Posted December 19, 2015 good..get em Quote Link to comment Share on other sites More sharing options...
italianstallion Posted December 30, 2015 Author Report Share Posted December 30, 2015 Thanks to all. Sorted now with high temp silicone and S3 specific orings that are not listed anywhere - pretty **** tbh, but a big thanks to BVM for sourcing them! https://www.dropbox.com/s/d17lix5c27ib6q1/_20151230_214105.JPG?dl=0 Quote Link to comment Share on other sites More sharing options...
