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 10 hours ago Report Share Posted 10 hours ago 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 1 hour ago Report Share Posted 1 hour ago 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.
