how can i get my head bolts out they have snapped ? derbi gpr?

I've snapped a bolt off trying to change an exhaust on my motorbike. I've been advised to drill into the screw and then use a stud extractor (although I am now going to try the 'weld a nut to the end' as suggested first).

Failing that helicoiling is the other alternative but try and find a garage run by two old men and ask if they can do it for you while you wait (cheaper that way).

maybe try a screw extractor? if you have access to drill a hole in the sheared bolt.
