First GET RID OF THE LOCKNUT ! It only pulls the gland nut AWAY from
the gasket ring and DECREASES the pressure you are relying on to seal
the joint. They MAY work OK if you have little wear on the threads but
you are far better off to PROPERLY tighten the gland nut WITHOUT the
lock ring. The original chrome plated brass gland nuts were very easy on
the aluminum threads and also had a higher coefficient of thermal
expansion which actually caused them to hold better when hot.
A properly tightened nut will hold until you WANT to take it apart.
Most of the problems come from people afraid to tighten them fully for
fear of stripping the threads. A little high temp PERMATEX ANTI SIEZE
and a LOT of ttorque with the PROPER tool are required !
Pipe wrenches , spanner wrenches ,hammer and punch , basin wrenches
etc. are NOT the proper tool. A castellated wrench that drive on the
TANGENT is the best way . The others tend to distort the tubular gland
nut long before the proper torque is achieved. They may work now and
then but to be sure the good tool is a must.
If you don't have access to the right tool ,email me and you may
borrow mine. IT WILL WORK !! :-)

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. cookie ----- Original Message ----- From: "E.
