Heli-coil kit for stripped spark plug hole

The M14 x 1.25 Time Sert kit I purchased used last year off ebay:

Whoa dude, you might want to delete that one.

Had to use my wife's laptop to do it. 

Probably not a good idea to copy/paste images from past forum posts...which is what I initially did.

Whew!   

That's definitely the "gold standard" of insert kits

Why delete it?
 

Steve, I reposted the image from my phone after attempting to copy/paste it from a previous KZR post on the subject.  That method produced a mile of illegible code that took several edit attempts to delete.

GOTCHA 

Maybe it doesn't matter, but Timeserts are thicker and have more mass than a small insert like a helicoil.  I've read that they can affect heat transfer through the plug.  They sell aluminum Timeserts, and I wonder if those would be a better option for an air cooled motorcycle?

An interesting point Ed but I would come back to my original question, the OP said the 14mm coil was way to big and to be honest in the picture at least, that looks like a 12mm plug next to the 14mm coil to me. If that is the case it's no wonder it blew out 

Went with a NAPA-sert and a tap, so far so good!! Much thanks!

I repaired with wurth many years ago works perfect since…
