My suggestions, if you feel like experiementing.

1) locking nut. but this time undo the locking nut and tighten the outer

each tank fill. takes 2 minutes.

i'm not there when my mate fills up.

2) locking nut. try two gaskets. yeah it's a long shot.

thought of that. seems a bit desperate, but will prolly give it a go soon.

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.

i charged mate 40 quid (what they cost me) for the locking nuts. he's gonna
want to use em.

just a thought.

when i do them up, they are tight. headers are fixed tight to head. when

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

certain extent, and helps the nut stay put a bit longer.
My locking exhaust nuts still come loose. Even though the lock nut

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

the exhaust nut comes loose with the lock nut while I'm loosening it
and

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...

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

the threads (tip from the list!). The combination of these three
things seem

make my gaskets last a bit longer.

Has it got the frame to exhaust pipe clamps?

Subject: exhaust probs

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

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

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

than

stock.

i must have put 6 sets of ex gaskets in that bike & i'm getting
fed up

now.
