    I Searched and searched but...

    My slide vacuum holes have been drilled out to 3.5mm(ish, it might be imperial), I'm looking for the original size of the vacuum hole in the slide for the Mikuni BS35.

    Thanks in advance.

    Found an undrilled slide.
    3/32" barely squeezes in and 2.5mm is too large.
