Hi Frank,
No, I locked the nuts high enough for the fork to pivot without making contact with the lower nut. The main purpose for the nuts are to hold the fork somewhat in place during installation and keeping it on when the clutch is not depressed. When actuating the clutch, the pressure on both ends of the fork keep it forced against the pivot. When releasing the clutch, the return spring would pull it off of the stud without the nuts.
I like your thinking though. If I had it do to over, I would probably round off the bottom nut and lock them closer to the fork. There might be a little rattling noise on mine when the clutch is not depressed, but I could never hear it with the engine running
