new front gasket thingy - What you talking about :confused:

round copper ring thing that goes on to seal your exhaust on the cylinder head I believe

i got myself a stud extractor for when i can finally get the pipe off to remove studs , at minute it wont fit on , impact type extractor

ive sprayed no end of wd , damn thing wont budge !!!

cheers for all the advice , im gonna try a blow torch next and heat her up see if that helps - petrol tank removed of course !!!

get some freeze and release spray too. Apparently heating it, and freezing it shocks them into coming out....perhaps you should ask YC...he did my terrible pain in the ass bike:cool:

Re: exhaust wont budge

Try a rubber mallet (gently) at all the connection points and mounting points, could be welded on with rust.

They came out complete with rust all the way down the threads, without snapping. What more do you want.. blood? :-P

The best way IMO is to grind the nuts off carefully so as to leave the studs intact, then to use heat, plusgas and patience to work he studs loose with a proper stud remover. i.e the socket type ones, or indeed 2 nuts but be sure you are turning not bending them!

My front downpipe was welded in with rust. I used a big hammer and a lump of wood to persuade it loose.

Re: exhaust wont budge

Didn't have this issue with my system, guess I was real lucky judging by the posts. My studs came out using the two nut method.

But I had the same problem with rocker cover bolts on my Guzzi Spada, so I sympathise with your issue

If your stud extractor method doesn't work, the you may need to resort to removing the front cylinder head and having the studs spark erroded out.

Sorry if this the worst case scenario, but as the others have pointed out, an easy out isn't going to shift this mother, and if it snaps you realy are stuck.

Another possiblity is having a nut wealded to the stud, the combination of heat and having something solid to slip a spanner onto, might just do the trick. You'll need someone handy with welding gear

Re: exhaust wont budge

Yup MIG it or someone who's reasonable with oxy torch.

A new head is likely to be a fair bit cheaper than 2 spark erosions.

Re: exhaust wont budge

Thread resurrection!!

Got the Exhaust nuts off, Exhaust off and studs out no problem.
Only trouble I'm having now is how the hell do you get the stud out of the stud extractor????
It's one of those socket type ones with the eccentric holes that tighten up on stud.
