???? Did I miss something here, Mark? I don't see anywhere in this thread where any of "us guys" said you should replace any Helicoil inserts. We've pointed out that there have been cases of helical inserts pulling out, and that there are other inserts that some of us prefer for their extra holding power, but I don't see anyone telling you to replace anything that's still working. No flame intended here, just a little clarification needed.

Ooh, I'm sooo embarrassed. Dave M nailed it. When the torquing "went soft" on me I assumed (I know...) that the culprit was a failure of the aluminum in it's tense battle with steel. It was the long nut that stripped. I disassembled all and the stud was just fine. Like I mentioned, I don't/couldn't know the provenance of my bike, but I suspect the long nuts were aftermarket. They are pretty chrome, but one deformed where the face met the head and I needed a 9/16" wrench for one because it was to big for the 5/16 BS that fit the other. They must have been pot metal knock offs from Outer Slobovia. Anyhow, I have some good SS replacements on order from Ella at Old Britts. Thanks for all the thought and input. And yes, a real bummer about David Bowie.
you gotta love this forum !

If you're asking about my avatar, I first saw this photo in the back of a Cycle World back when they did a funny last page. It was captioned "Sirens were a popular option on the Excelsior Henderson." I wanted to blow up a copy for my garage art and found it on line but could not get a clean digital copy until I contacted the Pres. of the Excelsior Henderson club. He sent me a clean digital copy (I had iPhoto blow it up for my garage) and told me what he knew about the photo: that it was taken in Hawaii sometime in the 20's and that the woman on the back was an early feminist and was arrested in Michigan for indecent exposure, wearing the same outfit in the photo. You're in Anacortes. You need to join the Washington Vintage Motorcyclists!
I had a problem with this same stud with the resulting oil leak a few months ago. Head came off & was sent to Jim (commons) for a total go through including valves & guides & inserts etc. Also checked for cracks in case the oil wasn't just seeping because of the stud being loose. When I pulled the head the stud was oily & loose but didn't apear stripped but subsequent torquing of the nut didn't keep it from loosening after a day's ride so that's why I pulled it & sent it to Jim. My exhaust threads show signs of a less then perfect past repair so I had been wanting to send it to him anyway..

I'm familiar with the Washington Vintage club. I gave a lunch-time presentation to them on my experiences at N-V a few months ago. I haven't been an active motorcyclist since we emigrated to the Seattle area back in 1968. There are so many poorly-skilled car drivers out there, I just didn't feel safe riding on what, to me, was the "wrong" side of the street.
With 4 children and a very busy job at Boeing, I just didn't have the time to pursue it later. Now retired (and 74), I don't think motor cycling is for me any more.

Alternative studs?
Hello,
I'm looking at redoing a helicoil type repair that's failing on my bike. I was looking at Klempf's site and he lists STUD, 3/8'', UNC/CEI THREAD Part Number: 06-7871, which would let me install a Timesert or similar thread repair and use the stock sleeve nuts, assuming the length was right.
However, in looking at Norvil's site the same studs are listed as either Whit/CEI for early engines and UNC/UNF for later engines, which sounds more plausible. Does anyone know who's right?
