These things can be incredibly difficult to pin point without hearing it in person...

But do you hear it at idle? When you rev it in neutral? When it's in gear with the clutch pulled in? While riding? Need some more info...

Yeah put you foot on the header and see if that helps.

They aren't the quietest bikes. I water earplugs and it sounds terrific when thrashed.

If it's only while riding then probably chain slap on the swingarm slider.
Many have been befuddled by that.

Yeah that's secondary vibration. Push your foot on the pipe and see if it quells it. A mate had radiator braces that touched the pipe and sounded just like that. My pipe guard clamp stripped and I fixed it just after last ride. Can get rattly up the manifold.
