I have a right-hand exhaust header on my 850 that is tight when using a new copper washer but gradually works loose. The collar is tight - and I am not keen to use anymore force on the Norton spanner to try and tighten it more.

Is everyone using standard exhaust gaskets or is there something better?

I did see in another board that someone recommended thicker Suzuki gaskets from the GS range.

Any suggestions other than puling the head and using heli-coil inserts?

Hi Tony,

Using the the correct tool that I have, I usually find that after a coupla tightens when the head is hot....no problem.

The trick is to retighten a couple of times when hot & it stays put........usually.........

Dunno about the suzuki gaskets myself but should not be necessary.

I have seen wire holding them in place, springs also, drilled n tapped(ugly if not done neat) & the proper norton exhaust clip also(but they rattle) !

I admit to drilling the heads in some bikes I have owned, the best palce if u do is inside down low so it is harder to see :idea: A neat lil spring looks best in my humble opinion.

Many choices.........but I do carry my exhaust "tool" with me whenever I am on the bike nowadays as I refuse to drill these two heads.

I dont know about "better" but the gaskets used in many Japanese bikes are basically the same size, and will fit a Norton, the only real difference being that they are substantially thicker.
I cant remember which are the best but if memory serves me correct the ones I had here for a Honda CB750 would fit nicely.
If you had issues with leakage using stock Norton gaskets You could try a set of these, at least until you had time to pull the head and do a proper fix.

I'm pretty sure I used to use GS750 exhaust gaskets in my old 850 (I bought a '79 Suz GS750 which ended up replacing the 850).

I've read that replacing the headers with the 750 style (without the crossover tube) will help. I've also read the 750 nuts are slightly larger in diameter, meaning they're a better fit and less likely to strip out. DD or someone might know more about that. I read a lot of things but who knows if any of it is really true :)

On my 850, the nuts were always coming loose. Eventually the threads stripped out and I had to pull the head and send it out for repair (welded inserts). No problems at all on my 750 though. So far anyway...
