So when you say machining off the sprocket carrier wich part of the carrier gets the machining? Could someone post a picture?
You will most likely need to remove material from the surface the sprocket sits on (this will involve shortening the sprocket mounting bolts as well) however you first need to mount the swingarm and wheel in the bike and centre the wheel, then fit the front sprocket. Only then can you accurately measure how much material to remove.
