So i was changing the oil on my gs500 yesterday. i was nearly finished and screwing on the filter cap. I screwed on the 2 nuts out of the three just fine. As i was tighteing the third nut, it continued to spin, and just fell off. Well the bold or stud thing or whatever you want to call it that the nuts for the oil filter screw on was completely twisted off. I dont know how it happend, but now when i run the bike oil leaks out pretty badly.  Are the studs replaceable? I really hope so, becuase id hate to ruin a bike becuase of a stupid case of overtightening. HElP!!!

Take the oil filter cover back off and see if there is still part of the broken stud sticking out of the engine.  If so, grab it with a pair of vice grips and unscrew it.  If not, you will have to drill and tap or helicoil the hole.

Try a search, this has been covered once or twice before! It is repairable.

Yep......must be almost 2 weeks now since the subject of this problem was last brought up 

As I am sure this has been covered before. I would recommend that you find someone that is experienced in doing this broken stud removal, or bite the bullet and have a shop do it. While this precedure in not too difficult it is rather important and can eaisly be made made worse without the proper tools.

A stud removal kit can be purchased at most auto parts stores. If it is really tight and does not remove easy then drilling it out is a little more difficult. Caution: No matter what you attempt take care not to scratch or gouge the metal on the case around the broken stud.

I did that a while ago. My local shop refuses to do them. In fact if they do it they call in a stud removal specialist ($60 and they gave me his number).

What I did instead was get 2 nuts on the broken stud (just fit) the uses a spanner on the lower stud to remove it 1/12 of a turn at a time, using the top nut as a locking nut. Took me about 10 minutes to remove it. Those studs are super soft so they break before the block gets ripped apart.

Roger that assuming you have enough threaded material that is a great method. Thoroughly soaking in "Liquid Wrench" or simular break free substance helps a bunch too! Multiple applications of this the day prior works miracles!

But I can't stress enough to the first timers how important it is not to mar up the surface around the stud. This is a mechanical seal and needs to be flat and smooth for proper seal.

This has been covered in great detail in other threads but it does not hurt to cover it again since he asked.
