Broken exhaust studs - Page 2 - SV650.org

It's fixed! Used wire thread inserts. Not a happy process but thanks for the advice. I rigged a kind of jig for drilling out the first one and then used Viney's suggestion for the second. Nor perfectly centred on the originals which made me sweat but there's enough tollerance in the bits to let it work. Hope it lasts.

I can't stress this enough: Unless the nuts come undone immediately and with little effort, (very rare, but not completely unknown);

DO NOT CONTINUE.

We've been here several times, the only certain way to remove them if they're at all troublesome is to cut them off, it only takes a few minutes and will save you a proper headache.

Add to this that the rear pipe has a sleeve gasket section - there's usually no need to remove the nuts/studs anyway, it certainly isn't needed to remove the swingarm or the engine, and if you have removed the engine the rear studs are as easy to work on as the front.

If I had thought about this, I would definitely have used the sleeve gasket option.

My exhaust was retained at the engine by allen bolts so the cutting off option didn't exist.

Mine are bent, does anyone know the size of the stud and where they could be bought online? Will robinsons do them?

cheers

They are M8 x 25mm

You can get the studs from Robinson's, best to source some stainless steel ones and some stainless steel nuts though (Curvy).

Cheers Dave, I don't have a clue where would do stainless ones (and gear change rods - save on postage) would shed loads of copper grease do the job?

I have the OEM ones fitted in my Beasty, copper grease between the thread of the stud and (titanium) nut plus a coating of ACF-50 on the rest of the area has caused me no problems.

Some one on here has a link to SS studs.

Stainless M8 threaded bar is easy to find. Want me to make you some up dave200? Can send them with that cover.
