Stuck chain adjuster

[BigKX]

The previous owner of my KX500 neglected to put anti-sieze on the chain
adjuster bolts.  Needless to say, one of them snapped as I was trying to take it out.  How do I get that sucker the rest of the way out?

Try screwing out the rear brake line holder on the swing arm and fill it up with wd 40. Screw extractors? Little heat as well? Getting a drill close will be the problem unless  you have flexy extension thing.

to big,
you snapped the head off the bolt right, and the jamnut is loose.? all you have now is a portion of threads showing.? well it's trashed now anyway, i hate to say it but, grab the threads directly with the jaws of visegrips or channelocks back it out this way, replace the adj bolt with a similar length replacement, metric of course.
** the ez-out bit will work too, provided you can get a straight hole drilled to turn the extractor. don't let that kinda thing slow you, jdv500
