IDK about y'all but once my RT got to about 24k miles, I didn't have to touch my valves despite checking em every 6k. Traded that bike in with 50k miles on it.
The GS-Adv went the same way. First few it was important to check and adjust. After about 24k again, I kept checking, but they weren't moving.
I'm a cyclist that rides motos, not a moto rider that rides bicycles.
