Question about idle rpm's

rij1
I'm wondering if any else's bike idles high when hot. Hot like after riding on the freeway for say 10 minutes. My idle runs up from 1000 cold to 2000 hot.

Sounds like it is developing a vacuum leak when it gets hot.

Or it could be running a tad rich. Thats a symptom of it. Once the engine hits operating temp it can burn the fuel better so it'll idle higher.

Hmm, So I should check the boots for a vac leak. And Maybe close the pilot screws some.?
