mollygreen Posted June 15, 2007 Report Share Posted June 15, 2007 Can anyone out there tell me where I can get hold of some rubber fin dampers for the barrel fins of my TY250 T/S? The type I am looking for are the solid rubber bar type that fit in between the fins. Quote Link to comment Share on other sites More sharing options...
kevin j Posted June 15, 2007 Report Share Posted June 15, 2007 The bar that has several 'teeth' on it like a comb? I've also tried to find. Not many in salvage yards anyway, and what I found the rubber dampers were usually gone. I just went without, but thinking now. Could you take a piece of solid rubber chute lining (like conveyor belting, but no cords in it, it's available up to 1 inch thick) and carve it with the cutoff wheels in a dremel. Nice and slow, and keep it cool. kcj Quote Link to comment Share on other sites More sharing options...

I live near Sammy Millers, so I went in and asked Sam about fin dampers. He showed me a Bultaco damper that is a block of five rubber "teeth" that are joined together. They are designed to go length ways between the fins of a Bultaco barrel all in one piece. They would not fit my TY barrel because they were too fat, length ways, but cut with a modeling knife into sepereate segments and fitted width ways, they were exactly the right size for the barrell fin spacings on my TY250. So, to cut a long story short, I bought 10 of these blocks and cut them up into 50 pieces and fitted 47 of them in between my barrel fins. They have worked extremely well and have quietened the resonance of the fins no end. I am very happy with the results. A bit fiddly to cut up and fit individually, but well worth the trouble in the end. Quote Link to comment Share on other sites More sharing options...
trialsmm Posted June 21, 2007 Report Share Posted June 21, 2007 (edited) I have used black RTV silicon. Just press out between the fins, let it cure and works! Edited June 21, 2007 by trialsmm Quote Link to comment Share on other sites More sharing options...
