I was just checking in to see how it went for you, and am just bummed for you reading this.
Something for you to ponder, though:
I picked up an old Ironhead this summer and one of the first probs I found was a stripped primary drain plug.
(There is a thread here somewhere with some pics of how bad the the plug was f'd.)
What I did was go to O'Reilly and bought a "Self-Tapping" plug - one size up from the original size.
And being REALLY careful, I tapped this in.
(I mean REALLY CAREFUL... Had some help to ensure it went in straight.)
Then I ran some oil through to hopefully take out any debris.
It has held flawlessly since (I have done 2 oil changes since).
Again... if you want to consider, get Dave or Schmidty on the horn to see if they think this is a good idea..
DO NOT DO THIS ON MY ADVICE ALONE!!!!
Get some opinions as to if this is advisable.
...But it was a good $7.00 fix on an admittedly "Non-Important" project for me.
Good luck Man.
