JVB is right. Remember, the stock system uses a steel bolt shouldered with a stop, tightened to very low torque, threaded into buttery aluminum. Used properly, this works for the life of the bike.
When a repair is needed, a Helicoil (or similar) will easily work for life inasmuch as steel is now the material comprising the working female thread.
When installing my OHV covers, I use hand snug for these bolts, no more. Bottom the bolt to the shoulder and then give a small additional snug...no more! I use a screwdriver style handle with a square drive and a hex wrench.
Done this way, you'll not be asking which thread repair system to use.
