Think metric it's japan.The Dynojet bit that comes with a stage 1 kit is a #30 bit at .128" (or close to that), which is what I have, so it's smaller than that.
My intention is to revert back to the smaller hole without buying a new set of slides.$$$
5/64 maybe??
I think that's the size of the Dynojet drilled hole, a number #29 or #30 bit - DJ calls it a DD19 just to be cryptic.
Stock has to be something smaller, maybe #40 or so??
