1) locking nut. but this time undo the locking nut and tighten the outer at each tank fill. takes 2 minutes.
2) locking nut. try two gaskets. yeah it's a long shot.
3) stock. to heck with it, go back to stock nuts. but this time at each tank fill give them nuts a good tweak (har har) I found I was getting a good 1/4 turn out of each one for the first half dozen tank fills. I would use the hook wrench (*gasp*) when the motor was hot. now I have no problems.
just a thought.

when i do them up, they are tight. headers are fixed tight to head. when he brings it back, headers are rattling about in the head but the nuts are still tight. they have not moved. deformation/erosion of the gaskets has created the gap.

In thinking about this I wondered...could it be that the nut *seems* tight, but isn't really all the way in and the headers are bashing slightly back and forth, hammering the seal? Perhaps thebottom couple threads are buggered or carbon clogged? Maybe a dremel with wire brush could help that?

i've seen similar on my friends bike. i assume the gasket has flattened, not the manifold nut come loose. don't see how it can tighten itself up.

Well, I think at one point we came to the conclusion that it would helps seal, reduce vibration through the threads and make up for wore threads to
a
certain extent, and helps the nut stay put a bit longer. My locking exhaust nuts still come loose. Even though the lock nut is
tight,
the actual exhaust nut backs it's way out a hair enough for the engine
vibration to waste the gasket. The only real way to tell this is by loosening the locknut. Then I can clearly see that the exhaust nut decided to run away again. It's weird, I know, but I have been careful
to notice
if
the exhaust nut comes loose with the lock nut while I'm loosening it and
it
doesn't. It does it all on it's own. I probably got some real wore
threads.
I would suggest you try loosening the locknut to see where the exhaust
nut is at, if you haven't already...

what's the RTV supposed to do?

ps i got the locking nuts on my own bike & i never have to touch them or
the
gaskets.

If you got the frame clamps and the locking nuts(I got 'em too but I'm
not
quit sure if they were worth the $$)You can try some hi-temp RTV on the threads (tip from the list!). The combination of these three things seem
to
make my gaskets last a bit longer.

Has it got the frame to exhaust pipe clamps?

to whoever wrote this (i've lost track):
"cookie I always thought exhaust if it pops letting off the throttle
and
intake air leak if it popped getting on the throtle? B."
an air leak at the exhaust manifold will pop on the over run. an air
leak
on
the intake will just make it run weak in my experience.
now if anyone knows how to stop an eldo getting a loose joint at the head/downpipe i'd like to know. got a friends bike doing this all the
time.
NOT the nut coming loose (it's the locknut type), it just eats the
gasket
after a few miles, air gets in, backfires like crazy. i put new
gaskets
in
&
it's fine for a while, then same thing.
it started happening when new mufflers were fitted with rear balance
pipe
removed. i think it may be to do with the pipes moving & flattening
off
the
gaskets. however the exhaust assy doesn't appear to be moving any more
than
stock.
i must have put 6 sets of ex gaskets in that bike & i'm getting fed up
now.

I heard a little while ago that the popping could be from looseness

the exhaust is tight up there, and/or has no leaks.
