400ex stock carb flange size

[400exstud]

Does anyone know the stock 400ex carb inlet and outlet flange outer diameters? I'm in the process of building a MegaSquirt EFI system, but I just relocated to Michigan and my ATV is in Wisconsin. I need these measurements to start planning the fuel injection intake.

Thanks!

Don't know if you still need these but I was out in the shop earlier for a couple things and decided to pull out the caliper to help ya out. Airbox/intlet size is 2.32" and the Cylinder/outlet size is 1.72", didn't know if you needed inches or mm.
