Bobwire, if you have access to a bead blaster, and you have that many sets of barely used...probably worthwhile in THAT case. When doing high speed "chops" when testing and setting up A/F mixture, it is perfectly fine to use them. If not fouled bad, properly tuned engine would have them cleaned up pretty quick anyway.

If for some reason I have mine out and they ran fine, showing No problems and new enough yet,,,,,

I take a stainless brush to the electrical spark end of plugs, also brush Clean the threaded ends, check gap, Put a dab of silver anti-seize on the threaded ends and re-insert them to a Tightness I feel is tight... Probably close to the right torque specs.

I only use the stock HD plug and Nothing fancy or $$$$ more, as these Stock plugs work Best in the Harleys.

I have Tried ALL the plugs offered over the years (lots of snake oil) and the stock ones have Always work best for me and are cheap enough to replace Often.....

I replace mine as part of my fluids service. Engine oil, tranny gear lube, primary fluid, oil filter and spark plugs every 3k-5k miles, but aim for 3k.

TQ
 
Remember the crush gasket on an old plug is meant to be torqued only once it helps in heat transfer and makes a good seal for compression:s
