Jealous Lover?

[adamod_imp]

My 2017 has been out no less than once a week (average ride is 100 miles, odometer is 7k) since buying brand new 2 years ago. The last three weeks CB has sat in the garage unused. Today I jumped on turned the key and found a dead battery. Charged it, started it and the engine sounded like Patti and Selma after singing We Love To Smoke. Water spewed from the pipes. CEL came on and revving beyond 6k was not possible. Turned it off and left it alone. 20 minutes later it; started immediately, sounded great, no CEL, revving was at my command. Then, took it out for 80 miles with no complications.
What happened?
What did I do wrong/right?
Does this beast need to be turned/ridden everyday to stay happy?
Do I have a jealous lover on my hands?
