The only time I replaced plugs was on my '76 Yamaha RD400 two-smoker. Sometimes I just got lazy.
All my other rides never saw plug changes. Yes, perhaps cleaning/re-gapping, but that was it.
With many larger bore modern lumps with a pair of plugs per cylinder, I reckon the probability of getting a spark is better. I definitely never changed plugs on those configurations.

Had 2 sets of spark plugs ordered a few days ago, and took the old ones out today. They look like Max's plugs. Given that the plug type for the CB1100 is a special one, and there aren't many CB1100 around, I figured it's good to have spares for such plugs which no other engines need. But when I look at my old spark plugs ... I guess I am now equipped for at least 150,000 miles on the CB1100.
