Interesting, here is a picture of my flywheel. The "cutout" measures 31mm. I asked a GasGas tech about it and he said that it is "stock, and should be fine".

I assumed that it was already modified. You can see where it looks like grinding took place to elongate the "cutout" (which I assume is the sensor window). But Duster says his gap is twice that long (?).
Here is a picture from another forum. It shows a "before" and "after" picture, but the post is unclear as to which is the modified flywheel. Does anyone know the correct cutout/sensor window length?
