I just picked up a 74 Eldo that had a aftermarket accessory on it. It was
a finned exhaust clamp similar to the ones on the old brit bikes but the
inside was turned out so the stock guzz exhaust nut wound fit inside it
half way while the other half was tightened around the exhaust pipe. Neat
Idea, to bad the fins were broken off of it.

I have lockwired original manifold nuts with stainless wire in the past,
and
the sods still moved. maybe that's a reflection of my lockwiring ability,
dunno? seemed ok when i did it.

never had aftermarket nut with lockring move. important to use a proper
wrench on them though, don't just belt them with a hammer & screwdriver.
urgh!

 Yeah, I've thought about that in the past and I'm just being a wimp about
it
 but I don't really want to drill the heads for something that might not
improve the situation. But I'm still tossing it around in the 'ol noggin
and
 mybe when the project bike is done I'll screw around with it.

Why don't you try and add a lock wire to the whole exhaust nut lock ring
combo. Would certainly help to prevent it from moving then.

 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...

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

it pops through the mufflers. I have played with the air screws and

Someone

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