The SM states these Iridium plugs are not adjustable and replace if beyond .040" w/round gage or contaminated. All plugs 'contaminate' but are not replaced for that reason.
Mine are both @ 8K miles w/the SM saying inspect @ 12K and replace @ 32K. There's also a .039-.043 gap range so they're well w/i range.
The bike runs fine and will clean and put back in. The electrodes look good, are not rounded but don't understand the non adjustable/contamination entries.

The SM is wrong if it says they’re not adjustable. I’ve adjusted them. They adjust the same as any other common spark plug.
