See post # 2.
FWIW every 10K miles if using copper plugs is keeping optimum new plugs always in the bike.
If not on a budget, I think Harley charges $7.50 each for OEM plugs, then just follow the manual which I recall is every 20K miles.
Then there is plug indexing...easy and great fun.
As a hobby, sparks plug replacement this is so easy, so why not?
Have fun.
