I didn't retap head studs, but I retapped my rear motor mount hole. I broke a threaded rod, I tried left hand bits no go.
So I drilled out the remaining threaded rod. I don't have expensive tools and am not going to buy any lol. I took a 6mm bolt and 2 cycle oil and rethreaded the hole with it. The threaded rod is holding 10x better then the original hole. The threaded rod has not have me any issues since.
I have rode close to 100 miles in 2 days and am so happy now. Oh I used a 13/64 drill bit, a 6mm bolt and a ratchet.
