Here's a carbide set of numbered drills, these won't follow a hole as much as HSS and they'll bore it, need a drill press for these for sure but yeah got sizes bigger than what you need in jumps of .001 which is two jet sizes
The first link is mostly useless, it increases mostly by .05mm, again that's not ideal for getting a custom 83 jet, or 87.
Your second link is quite a bit more in line with the idea I already provided, cutting, measuring with a caliper ect...
However the second link says "let's use drill bits!" which is not the point, I own the set in the first link, not effective in all cases, second link just proves I had a point.
I don't even use pin vices! Stop mentioning it like it was part of the threads point. And of you look through an assortment of pins you'll find a pin with a diameter correspondening to a jet size, usually very quickly, once you get used to looking at it, then prep is easy and you can cut jets on the fly, even on the side of the road with nothing but said appropriate pin and a screw driver, it's just that easy.

When alternatives to a given and time tested procedure are offered it might be a good idea to explain that it isn't absolutely necessary and a simpler solution is available.
If you want to continue this discussion I suggest you contact me via a PM.
As far as less mechanically inclined folks go, don't be talking about defending their inabilities and then talk about pin vices and then defend members who are posting links describing exactly my so called advanced techniques, all in the same thread buddy.
Anyone who's in need of an 80+ jet had to of done interpersonal modification of said motor just for it to require that jet! Jesus I think if they pulled that off they can use a needle, caliper, and a drill.
Common sense people, it's free, use it.
