just drill the head off now theres a good chance once thehead has gone the rest of the bolt will be fingertight or a pair of pliers will grip the remaining bolt piece and turn it

Buy a left handed drill bit as that might actually unscrew the bolt whilst you are drilling off the head.

What material is it screwed into. Very difficult to drill steel bolts out of softer materials without cocking it up. I would centre punch the broken extractor then use a left handed drill bit. Apply some heat from a mini/kitchen blow torch first if you can do it without melting something plastic.

Just a note. When replacing that bolt, use an A4 stainless not an A2 stainless, much better and not that much more expensive.

These Irwin extractors are really good cos they grip the outside of the bolt

That looks a handy set of extractor sockets. I might have to indulge.

They are mighty handy.
Irwin do 2 sets of 5 to cover all normal sizes. And they do bite in very very hard which is brilliant.
I have abused mine and then some. Wouldn't be without a set now.

Hmm . . . . . Is there room to dremel two flats on opposite sides of the screw head and then get an open ended spanner (or, in extremise, a good set of mole grips) at it?
Or, grind off the whole screw head (broke screw extractor and all), then drill out . . . . and rethread to one size bigger i.e. M5 to M6.
Or, ---------- // ------------------- ------------- // --------------- ---- // ------ . . . . to whatever size needed to accommodate a through bolt and backnut.
Or, ---------- // ------------------- ------------- // ----------------- ----- // ------- . . . . and fit a M4, M5 or M6 'Rivnut' - I have these, they're a godsend in situations like this. If you want to go down this route, I can do that at mine for you.
Hiya Phil … I gave the Dremel a go and there isn’t enough room to get in there … is the offer still open to bring it over to yours for more drastic measures??

Of course. Can you get to Ottery during the day? Make it early-ish p.m. if you can't. Thursday, Friday or Saturday suits me. I'm not weather dependant as have a heated garage
.
If possible can you bring a cordless drill pls? My faithful Makita has blown its battery and a replacement won't be with me for over a week. If you don't have one, I can borrow one. Just let me know.
I'll p.m. you my address.

Big thanks to Phil and his still unused Dremel extension shaft, drill bits, punches and magic hammer.
Job jobbed and my Africa Twin now has a little bit of Italian to her

You're welcome Dave, glad we sorted it. Your Africa Twin will be henceforth known as a Hondaprilia of course
.
For the record, despite all the technological wizardry and tools available we cured the issue c/o a WW2 US army-issue centre punch, a mark 2 ball pein hammer (probably also of 1940's vintage, I've had it forever
) and a mark 1 eyeball.
Never forget the old saying folks (the one that Roy invented - probably) 'The art of bodge, it never fails'.

Often forgotten, in many sizes, a hammer is a useful tool.
