They should call them Not-So-Easy Outs.

Time to trash all those stupid stud extractors I've inherited. They are always more trouble than they're worth.
This is what happens every single time:

Oh the joys of working on older bikes. 

F*ck me.
So Elrich's F2 isn't off to a good start. After having to tear down the entire motor just to replace the cam chain, I snap a bolt off in the case. then I snap a stud extractor off in the bolt.

Next time I'm just going to quit when I'm ahead and drill it out and heli-coil it before I make it worse.
Yes, there will be a next time. I'm sure of that. When you start working on 40+ year old bikes, you'll understand.


  1. Lefty drill bit > extractors.

    You might also try drilling that bolt out with a smaller regular bit and then fishing out the threads. Use a center punch to start the dimple, then carefully drill out the middle of the bolt.

    Re-tap to chase/clean the original threads. Finally, some PB BLaster will go a long way toward freeing up the old bolt parts.


  2. The bolt was loc-tite'd in there like it was never meant to come out.

    I don't have a lefty diamond tipped drill bit of that size and it was 4am so going out and grabbing one was out of the question.

    I usually just drill them out to the edge of the threads then knock the rest out with a punch and thread chaser.

    This time I got lazy and figured I could just back it out.
    I set the extractor and turned;
    it didn't budge so then I tried to take the extractor out and it just snapped right off.

    Stupid mistake, but it's a good reminder of why you really need to take your time with these old bikes.

  3. Damn. Loc-tite on casing bolt? Anti-seize would have been the better call. GL

  4. RED Loc-tite. It appears they completely filled the hole with it because it was in the bore of the top case and in between the cases too.

    They must have had 1oz left and figured, "well might as well just use the rest of it."

  5. weld a nut to the exposed bit

    1. that was the problem... there was no exposed bit. I have a snap on stud extractor that would have worked marvelously, but alas.
