Ah Sorry, Paul and Matt run Tyga (see link above) in Thailand and have most of your NSR needs, However, i should have asked what model it was, being a 16 it might prove a bit more difficult to track down, But its worth Emailing Matt (Matt@TYGA user id here) or give the Admin (Andy) a buzz, they may have some sitting around..or direct you in the right direction.

If it was me I`d get it ally tig welded by a good welder.

You can dress it up after & drill & tap a new hole.

Hell of a lot cheaper than a new/ s/h barrel.

I`ve got a spare barrel I got with my bike that someone butchered trying to drill out a snapped exhaust stud. I`m going to have the same thing done to it.

Did you get it done ?
What were the results ?
How was it done?
I have tried, but in this mechanically undeveloped country I couldn't find anyone who could remove a broken top stud.

I haven`t had this barrel done yet. I`ve had good results in the past.

Whoever drilled the broken stud in my spare barrel let the drill wander. So they just stuck a bolt through at an angle.
I managed to get the bit of the stud out that was left. So now I`m going to get the hole welded up & drill a new hole & tap a new thread.

In the past I`ve drilled out broken studs. Then cleaned out the hole with a tap. Have to drill it centrally.
If you`re not happy with the fit of the new stud after this you can fit a helicoil insert, you can buy kits in different sizes. You then drill the hole out larger than the original size. Use the special tap to cut a new thread. Then screw in the spring-like insert with the key which brings back the thread to the original size. You are left with a more hardwearing steel thread to fit the new stud to then.

Another method is spark errosion by a specialist.
I would`ve thought you should be able to find somewhere in Denmark to get one of these types of repair done?
