jet sizes in metric

[fj11.5]

Hi. All, just wondering what the metric sizing is on main jets, I have standard 112,s but also a slighly larger Size that's stamped 112 but a 1.5mm drill bit is a perfect fit inside it, so is no way a standard size

[fj11.5]

Could the unknown size be equalto a 115 or 117 jet sizes

It could have been drilled by someone else, also.  So really, it could be anything.  It could be a dynojet or other company's jet that uses a different numbering scheme.

According to this post, it'd be about a 130 mikuni.
