fivemeister Posted January 7, 2006 Report Share Posted January 7, 2006 My son is in the process of fabricating a new silencer for me, and although he has plenty of experience with car, train, bus and tram silencers and could wing it - he doesn't know about two stroke stuff and I want to get it right. So, Has anyone got a modern (WES type) silencer for the 240 that they have repacked? If so, could you send me a rough drawing of the internals baffle / packing setup so I can obtain a similar performance. Plus, does fitting a modern non standard silencer entail a carb jetting change etc? Quote Link to comment Share on other sites More sharing options...
mattylad Posted January 9, 2006 Report Share Posted January 9, 2006 Use a straight through perforated tube of internal diameter 1 inch. This is pretty much the standard set up for all tailboxes. Go smaller for smoother power, bigger for faster reving. Use a perforated sheet with as many small holes as possible, this helps sound absorbtion.

fivemeister Posted January 9, 2006 Author Report Share Posted January 9, 2006 Cheers Mattylad, just the info I wanted. We did some research on the internet and found out about the straight through design, but I wondered about the actual size (length / dia) of the perforated tube and the likely effects on performance - hence the query about the WES make, thinking that they would have the optimum size.

mattylad Posted January 10, 2006 Report Share Posted January 10, 2006 WES are all approx 1" diameter, as they make such a wide range there are clearly other solutions. Go with the basis and you will not be far wrong. Quote Link to comment Share on other sites More sharing options...
superhondaman Posted January 10, 2006 Report Share Posted January 10, 2006 I can supply you with the perforated tube and end cap from a WES 200 Fantic exhaust. They are used but will clean up and have plenty of life left. I broke the bracket off holding the end can to the frame so have orderd a new one.
