      Hi,
      I opend the case for port matching and enlarging the inlet.
      the stock inlet on my motor looks to be already bigeer (on the inside) then on many photos i saw here on the forums and in the how to guide, the diameter of the “round” part is 11.5mm
      here is the picture

      the question is:
      how deep i need to drill with 13mm?
      should i also enlarge the opening on the inside more? and how much?

      thanks!

      Eran

        You need to drill 18mm deep. Not more 😉
        You don’t need to enlarge the inside of inlet. It’s big enough for you cylinder.

              If you drill it to 13mm diameter and ‘flow’ the tube into the rectangle you’ll have a nice inlet.
