Engine sprocket offset

[Spare_Parts]

Anyone know the sprocket offset from engine center for the 2 strokes? I have a Zeda if that matters. Don't want to pull the engine off again to check if I can get away with it.

About 34mm to the inner side of the teeth on a generic unbranded 66cc with #415 sprocket.
35 and a bit if you grind it thinner..
