Exhaust manifold
on: 25 April, 2018, 05:26:33 PM
Hi, today I had new tyres fitted and when I came back home I decided to take one last look on my brand new PR4s and discovered that one of the manifold pipes had a "dent". I don't recall mounting the kerb or any abnormal noises and I was there when the new tyres were being fitted. It doesn't look like there is a crack/hole in the pipe. The revs at idle are normal no fluctuating of any kind, didn't hear any engine or exhaust noises. At the end of May I'm going on my first eurotrip, but now I'm a bit worried.

That looks like a sharp implement or alike has been in contact with your pipe.

On my previous bike (Fazer 1000) I ran over a large stone, which hit the under side of one of my down pipes.

It made a dent, but not a sharp Ďcutí like that.  :187:

It didnít affect the bikes performance.  :028:

Take the bike to a welder. Two minute job to fill a split that size.

Thanks for your replies:). Now a daft question: do I have to remove the manifold from the bike to get it welded?

Any decent welder should be able to fill that without taking it off.

Nah, polish the *downpipes* up and they'll look tons better.

The ding; well it looks bad but if it isn't split I'd leave it alone.  If you think it is nearly through you can ask a welder, he ought to be able to do it in situ although I can't see it looking too good on stainless.
Only do it right - no bodging please.   Keeper of the failed stator list.   John.
