Today was a fairly nice day, so I thought I'd change the oil before putting it away for the summer. I got the oil change instructions off GStwin and went to it. It was all going good until I got around to loosening the oil cover nuts. It was stiff, real damn stiff so I gave it a heave and wished for the best. It came loose and I started to twist it off. It was still a little stiff but I thought "No problem, its not that bad". So I continue and SNAP MUTHA F*****!!! Part of the stud snapped off with the bolt still attached. And of course the Suzuki dealership clsoed 20 mins before I could get there so I have to wait till Monday. Anyway, how can I go about fixing this in the most sane manner? Will the stud come out or would it be secured onto something? Thanks.

Spray with WD-40.  Attach vise grips to the remainder of the stud.  Work it back and forth a few times.  Then turn it out a bit.  Spray it again, then work it back and forth again.  Turn it out a bit more.  Repeat till it comes out.

When a bolt or stud is seized, but but not under pre-load, the absolute worst thing you can do is apply more torque.  You have to baby it out.  Bolts and studs normally seize due to corrosion and dirt in the threads.  Working the fastener in and out helps to pulverize the stuff.

Hahaha the search function... what a revolutionary idea huh...  

Just go down to your local NAPA or equivalent, and pick up some new studs (using your broken one for thread pitch and length reference).  You don't need the dealer, plus they probably don't have any in stock anyway.

This is a common problem  - not just on the GS but on a lot of bikes.

The best formula that I have found for tightening these down is to tighten it until it *snaps* off.....Then back it off a little bit
