I safety wire the nuts on mine. Drill a hole in one of the fins on the nut. Thread the wire through this hole and then around the nut holding the front rocker cover on and tighten. You will be able to remove the rocker cover nut and put it back on without having to redo the wire. Don't drill a hole in a head fin. The wire can saw through it. The exhaust nut fins are much thicker so no problems with them.
