Snapped exhaust studs!

[gullarm]

My exhaust was puffing a bit so gave the studs a bit of a tweak.

A tweak too far and one snapped off, it looks like it has snapped off close to the nut and not flush with the block. Downed tools when it went ping to calm down a bit.

Now where is the best place to get a new set from, on lings the studs and nuts come in at £40 the studs are £1 and the nuts are close to £3 each .

Is it best to change the lot all in one go or just change the one. Assuming I can get it out.

Im going to remove the fairing later and check out the damage properly.

Yep cost soon adds up. You will find slightly cheaper pattern parts on ebay, maybe a local bike shop will have them if you dont want to go OEM.

If you have the time and patience you could do them all, depends on the condition I suppose. I find there evil little buggers and honestly as much as I would like to do all mine Im terrified of snapping them, I only done three so far. Its not a job to take lightly if you use your bike daily. I did have one snapped and had to use all sorts of methods, eventually after many terrified hours it came lose with one of those stud extractors and a couple of pieces of wire for extra grip.

Once you get em out, put the new ones in with copper slip in abundance.

A pain to get out....
If you have enough thread sticking out to get a nut on then the following MIGHT help.
Put a nut on the broken stud. Use a 5mm diameter drill to drill the end of the stud until it has cleaned up a full circle. What this does is give you an accurate centre to drill , say a 3 or 4 diameter mm hole about 12mm deep.
Take out the offending stud with an eezi out. (Worth soaking it with penetrating oil for a day or so beforehand, also, a hot air gun will help when you come to do the deed. (DON'T snap the extractor!)
Very important to get the drill on centre because if the extractor doesn't work you need to drill it out with a 5mm drill and try to pick out the first couple of threads before using a M6 tap to clean it out. If you end up cabbaging the thread, then it's a helicoil insert for you my friend.
If it goes really wrong and you are local to me (Warrington) then if you whip the head off I'll machine it back on centre and fit an insert for you!
Good luck

Good luck with the snapped one! I wanted to change all mine but was terrified of snapping after trying it!

Same thing happened with mine, but I was lucky enough to still have enough sticking out that I could clamp on some grips to it after soaking it with WD40 for ages and then slowly managed to work it out

I don't use studs and nuts anymore haven't done for years I use bolts and I've never had one fail on me yet.

You can just see them

Hi i always find the best way to remove a broken stud even if there is only a couple of threads left is to put a nut on the couple of threads and spot weld the nut to the stud then use a socket to exstract the stud the heat of the spot weld also helps to loosen the stud grip in the alloy head nope this helps rick
