Snapped exhaust stud :(

Howdy

Recently got myself a 1989 ntv600 as a winter bike (thinking ahead). 75k on the clock, been through the wars a little but all in all rides fine and looks ok. I started tinkering Saturday and tried to remove the exhaust. 3 of the bolts holding it on at the engine end (sorry, dont know the technical term) came off fine. The fourth snapped off!! The front exhuast hole of the 2 near the radiator now has a snapped stud sticking out. Any ideas how to rectify this would be much appreciated.

I had thought of this after a bit of googling

www.repairproducts.co.uk/page42.htm

My thought would be to glue a piece of threaded bar onto the stud and basically create a new one. Am i being adventurous or does anyone think this might work?

Thanks once again in advance. This website is proving invaluable

Whoops...

I wouldn’t attempt a ‘glue’ repair....
Try and remove what’s left of the old stud
and then replace it. You could do this by
using a blowtorch i.e. heat the area around
the stud and then use mole grips to remove it.
Or try using ‘Loctite Freeze and Release’. See
links below for more details:

As an alternative and more drastic method, you
could drill the old stud out then fit a helicoil insert
and new stud. It’s probably best left to a specialist
to do this work, so look around locally.
