I am in the camp with the "overthinking the problem" people & not saying that to be critical either.You heard that from a voice of experience which is often worth listening too. Yes , I did this sort of repair as a routine thing(as in for a living) & find the alloy stuff part of my reason for the above comment. As to Helicoils,timeserts, comparisons: there is a reason that there are not only different brands of thread repair items but also different choices with in a brand. I have seen perhaps 6-8 variations and all have their merits. I have used Thinserts & Timeserts often & choose them over helicoils most of the time but not always. This stuff is available in Europe & some made there too. The German inserts are sold on ebay and several other thread repair items there in small #'s/kits for home repairs. There are even "other brands" of Helicoil. The most common issue I find is what insert works with the metal left in the wall thickness or getting the depth I want. At times it is necessary to choose a new size thread over the original damaged one.
Too bad you are "on the moon" where you couldn't just get the originally suggested professional opinion , then go ahead with the fix yourself. My popcorns gone, good luck with the threads.

". what happens is that the screw catches part of the last thread, bends it, and the insert strips the part of the screw."


ahhh..... shorter screw? add a washer?

you are making assumptions too.
I am not "on the moon" but finding a place to keep my bike with the engine open whilst I go to have the job done would've been more of a headache than just going to my garage at the countryside and do it myself. not everyone has a garage where they live.
also, I had finished the job before you posted.
all went OK except that one of the towers broke when torquing the bolt down. maybe because of a bad torque wrench, maybe because of some oil that went to the threads and caused overtorquing. or maybe I somehow inserted the "spring" a tad too much and it reached the unthreaded end of the hole. not likely since the bolt rotated freehand but who knows. a point to pay extra attention to in the future though, provided I ever get to do a similar job. anyway that was repaired meanwhile and bike is up and running.

First, congrats on finishing the job!

Second, relax a bit ;-}

I don't recall typing with caps, bold or multiple exclamation marks that would indicate that I'm tense.

as seen from my previous post this turned not to be exactly a problem-free job. removing the caps, redrilling and retapping was a piece of pie but somehow that "tower" cracked so the "just go ahead and drill, grind, cut and then weep" approach is not exactly recommended. I'd advise everyone to do similar jobs with extra care.

Thread repairs are something I had the luxury of being trained to do,was paid for learning too & had great teachers from the "greatest generation" who were trained by others before them-point being , that when you're not trained, then it's tough learning on your own machine,over the web,etc..It can be tricky business, fraught with chances to cause expensive damages, esp. when engines are involved.
To offer a comparison, there is a reason I have always paid someone else to lay my new carpet, not wanting to learn on my dollar, even though it's not that technical. Glad your back in business!

Timeserts use the same size STI taps as helicoils for the same diameter fastener.

well wrenching is a bit of a hobby. I'm perfectly aware that a lot of things you only properly learn after doing them wrong but I'm up to pay the price. so far I haven't caused any disastrous or expensive damage.
as for paying the trained person to do it, I can't recall the times when I needed to re-repair the repair done by the professional plumber, just to give an example. or, having seen an improperly torqued rear axle nut causing the wheel to travel towards the rear of the swing arm that it's a wonder the chain did non break, and all that done by "professional" mechanics...
my sensation is that in the last years there's a tendency towards quantity over quality and that includes trained people.

Sounds pretty bleak? Truth be known we are well into several generations of non-professionals that cannot hang a picture on the wall!-all thanks to the move away from teaching basic tool skills & process, was called "industrial Arts " in my day.Same is happening to art,P.E. & music. We still have artists and so forth but some cause me to think they lack talent at times too. Used to be the future bankers & doctors,etc. even took some basic shop skills classes, what with many ending up as serious hobbyists too.
As one that taught people to "fix stuff" I can assure you, there are some pretty darn good ones out there , even today. Why don't you attend a tech competition and see for yourself that skill lives on. Todays' vehicles are designed for throwaway so it's a bit different in many respects(no rebuilding waterpumps for $6,e.g.) but still their are those that want to learn via use of hands & brain in combo. Are there those that are lacking, sure. A friend of mine employs a kid/guy that was a winner in auto body competitions. I'm not so certain that he would score high enough for Ivy people on the ACT but can tell you with certainty that he is a star in the shop! Actually quite an articulate person in the ways that matter in everyday life.
