Anyone ever repaired a Silencer ?

Post by Phil-UK » Sun Jun 05, 2011 10:16 am

Had a great weekend riding to a meeting in Dijon and doing a couple of track sessions but when checking my CB72 I find the baffles inside the L/H pattern ( David Silver ) silencer are rattling round.
Not talking about the piece that goes into the end of the silencer but the whole internal set-up.
Presumably due to high frequency vibration caused by sustained high revs.

I realise repairing it means cutting the thing open and rewelding things in place ( and rechroming ) but has anyone any experience of splitting these seam welded silncers ?

Guess the best way is to angle grind the seam and try to split but someone must have done this before ...... if I can find a way to do it then I could also reclaim some bashed up stainless silencers I was given.

cheers

My friend, Terry Ligget, up in Chesterfield has done this and I have a queue of silencers that I want to attack some time. His advice is to be very careful when you grind off the seams. Terry uses just a file and a flat blade to ease the seam open.

He is a master TIG welder so makes a great job of putting them back together but recons that the silencer halves are rather floppy when you've split them apart.

Good luck!!
