motopsycho87 Posted Tuesday at 06:31 PM Report Share Posted Tuesday at 06:31 PM (edited) Hi all, has anybody removed the baffle from their modern 2 stroke trials expansion chamber? Seems a bit odd as it's the worst place for trapping unburned fuel/oil mix, and kinda negates the point of an expansion chamber in the first place?

faussy Posted Wednesday at 08:12 PM Report Share Posted Wednesday at 08:12 PM Sorry, im no help. Now I know what's inside that front triangle section anyway. I know you can buy a more conventionally shaped aftermarket front pipe from s3 or the likes for the beta, that I guess doesn't have the baffle Quote Link to comment Share on other sites More sharing options...
jonnyc21 Posted yesterday at 04:56 AM Report Share Posted yesterday at 04:56 AM Well unless you want to let out all of the packing behind that baffle I wouldn't recommend it. I can't say for sure on the beta but all of the 2T bikes I have worked on have behind the baffle is one of a few different kinds of packing... Video of an older Sherco getting a re-pack.

motopsycho87 Posted 1 hour ago Author Report Share Posted 1 hour ago I managed to rip it out, turns out the baffle tube is titanium just like the outer. Took about 4 hours of hammer, lever bar and brute force. NOT FOR THE FAINT HEARTED! I repacked the silencer while I was at it. Started the bike up in the shed and very crisp note, slightly louder. I'm interested to see what it rides like potentially utilising the expansion chamber shape for the first time ever...! Quote Link to comment Share on other sites More sharing options...
