On four of my eight exhaust collars (CB400F) I have these
teeth in the past I plain put them in the way they came out and thought nothing of it, however in recent months (many) it hasn't been me who put the exhaust system back on so I went to the CMSL site to see if that would help but they didn't exist there. By now I'm taking a closer look at them and they aren't exactly uniform, like my own damn teeth even. It must be some kind of damage or mod by a PO. Can anyone shine any light on this
