The thou's fairing liner panels are notorious for it, and it's hard to pinpoint when you don't know what it is. Sounds like impending doom too, and all it needs is a bit of extra foam to damp it.
I have considered a vibration issue, and i was actually thinking it might be my metal radiator cover.
But after taking my lid off and sticking my ear near the engine it does sound internal when i get the right revs, and towards the top end of the engine.
I'm starting to get minor cam chain rattle again as well now, but i'm used to that noise and it's probably just between clicks. Remember i only commute on it so it takes a lot longer for the tensioner to go to the next notch 'cos i'm very rarely doing any motorway runs or ragging it at all, just going to and from work in traffic.
Noise still disappears when the clutch is pulled in, but if i shut off the throttle and let the engine slow the bike down the noise is still there.
I also found that i can hear it most down side roads when i'm riding in between parked cars, the sound is much more obvious.

Hmmm, that's a good shout, i'll look into that later and let you know!
Been a long time since the headers were last removed, i'll start spraying the nut & bolts now to reduce my pain levels in case they play up.
I just ordered some copper gaskets as well, it certainly won't hurt to replace them anyway.

Had a check of the exhaust nuts, and 7 moved okay so no issues there, but one seems to have gone completely wrong.
10mm socket spins easily over it, but a 9mm is too small.
And of course it's one of the hard to get to ones in the middle.
Looks like it's just rusted and disintegrated away on the outside.

I’m on call for work all this weekend so not gonna attempt anything until i’m ready to go all out to get the nut off.
I ordered some new nuts today as well. After a lot of searching about i found some at a reasonable price eventually, so i need to wait for them too.
I also have one of those sockets with the pins in that fit to any size nut, if i can get that near it i reckon that’ll get it off.
So weird though how it’s just rusted away.
They wanted £5 each per nut on Ebay, but i found a place up north that does them for £1.52 each.

They do that. I'm surprised you only had trouble with one.
When you've found a good fitting socket try heating the nut with a blow torch, just don't forget it's hot and burn your fingers when you put the socket on.
Socket with pins is your 2nd to last resort. Dremel or nut splitter (hammer and chisel) is your last one!

It's taken 18 years for this one to rust away, i'll think i'll take the chance, plus these bikes will probably be totally illegal in the future the way things are going :lol
Plus i was kinda hoping on having something like this instead
Changed the gaskets on the exhaust headers today......eventually.
TWO studs snapped off, flush with the nut.
To cut a long story short, hours later after plenty of drilling and making extended thread nuts to slip over what was left of the stud thread (my mates handy work) we eventually got it back together.
Noise is still there though :'(

I’ve replaced the front sprocket mid way through the chain’s life before. It does make a difference since it wears 3 times faster than the rear.
They're available with the rubber damper now for about £12.
