My MkIII is fitted with original Dunstall “silencers” that have been on the bike since I purchased it from the original owner in 1978. I understand that there were different versions. Mine are a straight through design with a 1” diameter or so punched metal tube runninng the full length that is removable. This tube has a punched metal baffle welded in about half way. The exit is the “Gatling gun” arrangement with a central solid rod in the center with a threaded hole and extending past the discharge tubes. The aft end of the exhaust is cylindrical w/o reverse taper. I have read some comments that the Dunstalls are quieter than pea shooters. They are not referring to my bike...
I’ve read that there was a baffle available from Dunstall to quiet them down. I assume that this would be a washer type piece that would be attached out past the Gatling barrels to partially disturb the exiting gas flow. Does anybody know the OEM part size(s) and looked like? Could wrap mineral wool around the internal pipe but I that would likely negatively affect performance more than baffle. Ideas/experience?
Thanks.
