Title: Mysterious Exhaust Teeth
Post by: Athame57 on May 08, 2024, 11:32:45 AM
On four of my eight exhaust collars (CB400F) I have these teeth  ;D 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

Has a previous custodian filed teeth in them to id for each cylinder ?

Perhaps owned by a dentist previously  ;D

But can it bother performance, compression et al?  :-\

No, they'll be fine George as the clamp down into the copper exhaust gaskets

Thanks Julie, point seen. Those exhaust gaskets though were one of the things that were missing when I first got Elen six years back, the teeth weren't missing like most of mine though!  ;D It took me a lot of finding out, as was the case with the starter clutch you told me I needed to get as well.  ;)

A lot of the time the old copper outer exhaust gaskets set like dark concrete and look like part of the head taking severe prodding and levering to remove, many times i have found 2 gaskets in the hole!

I had to a lot of probing and exploring to satisfy myself nothing lurked in the holes, and that the cheapskate in the past had not replaced them! I hope I got it right.
