Hi all,

My '71 CB450 has a noticeable gap between the exhaust flange and the engine, as shown in the attached picture. It just doesn't look quite right to me. Is that normal?

I'm wondering if there may be an extra-thick exhaust gasket smashed in there, or possibly a 10 year old one smashed on top of a 30 year old one, something like that. The bike came to me used, looking like this.

Please let me know if I should rip this apart and investigate, or if that gap is normal. Thanks!

Looks normal to me. Are you aware of how that goes together? The flange #1 presses against two half-pipes #2, which press against a flange on the end of the headers. That flange seals against the gasket #3, which fits into the port in the head. So, there has to be some gap, or you likely won't have a seal.

Rick's right - the only time I've ever not had a gap between them was when I'd assembled it wrong.
