Maybe as the previous post suggests a review of Keith Code's TTW2 book will cement the process of throttle control. I don't suggest you are applying power incorrectly. I'm suggesting that your understanding of what is happening using throttle, brake and steering input at speed while leaned into a curve is incorrect.
Close the throttle or apply brakes in a curve & the bike stands up. Application of throttle, even just holding neutral throttle, in a curve will stabilize the bike through it. KC explains it much more thoroughly in TTW2.
