I got screwed by the guy I bought my bike from. He stripped the oil drain threads and left the drain open. Bike is a 22 BD-125 grom clone.

Is the original drain bolt a m12x1.5? Not sure about the length.

Do you guys recommend a self-tapping oversized drain bolt?

And what are your thoughts on this

I've used a "Sav a thread" kit before but that didn't have a helicoil tag you had to break off. I'm worried about that falling into the engine. Unless I can leave it on?

All help is greatly appreciated, thanks.
