Topica Loopframe_Guzzi Archive

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 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

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 on
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
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

the

head/exhaust header joint, or somewhere close to that. Check to
make

sure

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

I am working on a 74 Eldo I just picked up with Amal Carbs.
When I

let

off the throttle and am gearing down
it pops through the mufflers. I have played with the air screws
and it

has

gotten better, but it is still

there. I have checked the carb intake gaskets and they are fine.

Someone

told me
this is a common problem with running amals on a Guzzi. Any ideas
