I too favor the left turns. I think for me it is psychological, in that if I blow a left turn I just end up on the berm, but if I go wide on a right turn, I might become a hood ornament.
I would guess that there's probably nothing wrong with the mechanics of the bike, but rather that something about your uneasiness is leading to the instability. I still consider myself a new rider (having had the bike for several years now, but not able to put as many hours in the saddle as I'd like), and I can really tell a difference between when I hit a corner with confidence vs when I enter it feeling "eeeeeh". Countersteering is counterintuitive, until you get used to it, and then it's natural until you start thinking about it too much. It is easy to tighten up on your grip on the handlebars, and while white-knuckling it, forget the "push to turn and look through the turn" and instead subconciously try to turn the handlebars where you want to go, which leads to a fight between you and the bike as your body tries to pull the bike one way and your handlebar input pushes it the opposite way.
As dumb as it may sound, go back to basics. Light grip, look, lean, and push. Even if you feel like you're in a lounger, you can still hang a butt cheek off the seat to get more turn without as much lean if you're feeling iffy about a corner.
Every time I feel like I'm going to go wide, taking a moment to relax and really commit to the turn fixes the problem.
Take it to an empty parking lot and hit those right turns hard. If there really is something mechanical, you want to ID that before you get pancaked.
