What jet size number the stock nt carb has???

Funny I was wondering about this and some related questions this weekend, and from a quick search of the forum I think it's a #70, but the manufacturing tolerances on the cheap far-east made jets are wide enough to drive a 4-stroke bike through, and they are nearly always a bit rich (too big) stock.
That's what I gathered from the threads I read anyway.

My stock speed carb measured #71 with a micro drill bit.
