Ok, after putting a couple hundred miles on it, the exhaust nuts on the rear cylinder came loose and fell off, and a couple of the clamps came loose as well. I got new nuts and replaced them on the rear cylinder studs and retightened the front ones. How tight are these supposed to be to keep this from happening again?

 

Tight enough to not come off. With new exhaust gaskets, you may need to tighten them up a bit so the gasket kinda forms.

I think you done good.

 

Assume you are talking about exhaust header nuts. Think they are harden lock type nuts? I know mine were since the flange pulls the ring and the pipe face seats on the copper wire woven seal ring.

 

I actually didn't replace the exhaust gaskets at the head since I am having the Indy replace the exhaust for me with the 2006 Twinkie take-off set he has and I was going to give him the new gaskets to use with the new system...

 

D1gger,

I want to thank you for this thread. I also want to thank all those who were involved and added so much info. I've been taking notes.

Any updates as to the outcome a few years later?

I started a new conversation on my issues here: '86 Tour Glide, EVO Main Gaskets Leaking

 

With Evos you need to tighten the exhaust nuts, run it for a few miles, let it cool down and tighten again, you may need to do this up to 3 times before they stop coming loose.

 

Spanner,

Should I add my situation and questions to this existing discussion from back in 2011?

 

Make sure it is not a cracked exhaust pipe, This past weekend I had to pull the exhaust because the header pipe cracked just where it comes out of the head, I could feel the exhaust blowing out but didn't find it until I took the exhaust off.. Just a thought.

 

Doesn't bother me....always good to bump a thread that is relevant rather than go over it all again if you ask me.

FWIW I have never encountered a pulled or stretched head stud but then bikes get messed with far less down here than in Americky.

Blown head gaskets can have many causes and the usual suspects as far as I can see are:

Incorrect torqueing of head at some point.

Stuffed base gasket

Cheap, nasty gasket sets (no name brand....you sometimes see them)

Very high miles

Overheating in parades etc.

 

Thanks Spanner.

I decided to start a new thread about my specific issues after all. I think it might get more answers that way.
