This mother f-er is being a serious beotch. Vertical cylinder on a 1995 900cc engine. Ducatis of the mid nineties were known for headstud issues. The horizontal cylinder popped a stud at the track and the broken one had to be drilled out then case was heli-coiled. I am changing out the vertical cylinder studs as preventive maintenance. Got 3 of 4 out and this last one is kicking my ass. I've broken it loose and turned it several rotations but then it reaches a point where is won't come any further. I've hit it from the top with a hammer to try to break it free, and also applied heat with a propane torch to the case area surrounding the stud. Just hit it with Kroil and now I'm going to walk the dogs, get some beer and see if that improves the situation (the beer, especially).
Suggestions for what else I should try...don't want this one to break...Major PITA.
