My first impulse is to grab a bigger hammer and aim blows in the general direction of the bike while cursing a blue streak.
Now that I've calmed down a bit, I'd use a center punch or drift and smack the broken extractor opposite it's "grab" direction, the on the sides in four planes to shift the bugger.
If that failed I'd get a bigger hammer and start over with the blows and swearing.
