Thanks Kioolt for posting. Nice to know that there is a way around eliminating the exhaust valve.

They also have an explanation of what the exhaust flap is for.

A good article and a cost effective solution. Thanks for posting.

Please don't take this as an endorsement as I only found it by doing a web search.

I asked that question, if you haven't made a contribution or its he second time on a warranty claim, that's it. No more replacements

yes this is the case as confirmed by the techs where I work

Do you know if they have changed the design with the new 1250 engine, looks like a different exhaust.

a few weeks ago Williams Manchester replaced my final drive as the paint was flaking, had the bike in for its two year service this week and they advised the exhaust valve was showing a fault  so they have ordered new headers under warranty.  Should be here in a week or two.
