Are you sure the starter is sitting firmly on the crankcase, with no small gaps? There should be a small peg adjacent to the N/S bolt and that can require encouragement to fit into the holes in the crankcase and starter housing. Make sure all is correctly aligned before tightening as the BSF threads in alloy are very fragile.
Are you sure the bolt is straight and not bent slightly?
Other than that, if all is correctly set up, you may need to ease the hole in the starter housing. Most of mine have been re-drilled to accept 3/8" threads but I wouldn't go that far, just a little easing may help if it's an alignment problem.
