Looks like head gaskets for the GS1100 8 valve are no longer available.
I'm looking at DIY copper head gasket videos, might have to DIY one myself if I need to.
Anybody doing this already? Actually I see Rapid Ray talking about them in posts from 15 years ago.
Chime in if you've got experience.
Thanks
 
I'd love to hear more, too.

Copper head gaskets are good enough for Allan Millyard, but then again he doesn't put monster miles on his wacko creations.

 
Here is a thread where a member made his own copper head gasket...

Thread 'Cu head gasket'

I would like to attemp making the h.g. in copper;
my question is: which thickness should I use, bearing in mind, I do not own (like most of us) a rolling mill - or a mill for that matter - to bring the plate to the exact tickness, so will have to be in one of the commercial measures i.e. 1mm 1,5mm or 2mm.

Could the heat treatment matter, I think in the hardened state, it would be eassier to manufacture, what do you reckon?

Also, do you think that, going all copper, I still need the two studs viton o-rings?

Thanks very much for your help.
 
Doesn't WISECO make a gasket?
Their site shows a copper one for an 1100G
 
Cometic supposedly makes one as well.

Let's just say that when I ordered a Cometic head gasket, long ago, the object that arrived was only vaguely head gasket shaped. It was shrink wrapped to a piece of cardboard, and the rings around the bores had sort of coned and stuck up about an inch. Why someone looked at this thing and thought "yeah, that'll do" and shipped it out, I'll never know.

I called Cometic and was told words to the effect of "tough spit" and "get bent".

Later on, I also used some Cometic gaskets on my KLR650, which promptly leaked.

Not a fan.
 
My Cometic head gasket has been holding up for 35 years on my 1085.

Plus, it appears Cometic has a copper one for his 1100
