I have an 03 KX250, it seems like my exhaust header pipe (chamber) is very loose at the connection with the muffler (where the rubber coupler attaches the two parts) The silencer only slides into the chamber about an 1/8" This seems very wrong to me. The mount on the frame for the end of the chamber (mount by the rear shock) broke off, I since welded a tab and got the mount back on. but even with the mount is does not line up, I have a FMF gnarly chamber on it and I know this is the model specific one cause I personally bought it. I was wondering if maybe the silencer was incorrect for the bike. I bought it used and noticed the silencer was connected with safety wire, like what you use on you bar grips I bolted the silencer back to the subframe like its supposed to be. and I am having all sorts of alignment issues. There is a Pro Circuit silencer on it, and I think that is stock maybe anybody have any insights on this?? Its really pissing me off
