Got it.
First, let me say that while adjusting the tps and the idle, I never at any time touched the handlebars or any cables.
Before I did this adjustment, I was riding the bike daily with no issues.
The reason I'm telling you this is because of how weird the timing of what caused my problem: my throttle grip shifted slightly down the sleeve and dragged on my Cycra hand guards.
When I parked the bike, no drag. When I adjusted the tps and idle, then put everything back together, the grip slipped and there was drag. It's just weird that at no time did I fiddle with any bar adjustment. I just don't get it. Anyway, the problem is solved.
