I have a couple of thread holes stripped on my gearbox AND timing cover. (fuck previous owners!) Leaking like a faucet. I have never used a helicoil (which seems like a $$$ rip-off in my opinion for what you get). The bike was set up for brit threads originally (66 T100), so I got the "set" that does 1/4-20. Pretty close. A couple of the holes I need to tap and heli are deep. Let's just say that a helicoil insert is roughly 3/8". The hole that I need to put it in needs about 2 and 1/2 inserts in to make it all the way to the bottom. How do I do this? It's a blind hole. The inserts have the "tang" on the bottom that the "key" fits in and turns it. How do I put the other coils in when there is a "tang" in the way? I know I can break it off as per the shitty instructions, but how do I get the broken piece out? I know this may seem like an idiotic question, but my feeble brain can't think of the answer.
