jonathan collier Posted May 11, 2008 Report Share Posted May 11, 2008 Just repacked the exhaust silencer, couldn't find any sign of restrictor bars in there, apparently not all of the restriction should be removed. Can any one enlighten me? A pic of what they should look like would be great. Thanks, Jon Quote Link to comment Share on other sites More sharing options...
john b Posted May 11, 2008 Report Share Posted May 11, 2008 Hi Jon I had one of the very first TYS125's (from Nov 03). I removed all of the restrictors and it ran no problem for the 2 years I had it, so personally I wouldnt worry. I know Birketts recommend leaving one restrictor in. All the restrictos are are around 6mm dia rods welded through the perforated tube. They are spaced down the length and they circulate the exhaust gas as it exits. cheers John.

jonathan collier Posted May 19, 2008 Author Report Share Posted May 19, 2008 Ah well seeing as the tube had rotted away perhaps they all fell out! Nice new stainless tube in there now, no bars. Quote Link to comment Share on other sites More sharing options...
