Is it a non-linearity in response, or some sort of random variation in response with the throttle held in a fixed position? In slow-speed maneuvers, there is so much interplay between throttle, clutch and rear brake, I'd be hard pressed to identify something as specifically power related.
And I could see that this might be a function of rpm, but I'm not sure why turns or actual speed would factor in. I'm not suggestung that the effect isn't real, just that I'm not sure I understand what the effect is.
The best way to describe it is, we're talking about throttle sensitivity/response and power delivery specifically when you're coming in slow to turn or make a U-turn. As you start to roll on the throttle, you may feel kind of a small hesitation or dead/flat spot in the acceleration, and when you roll into it further to compensate, you're greeted with a surge of power (snatch/jerk or twitch). If you're not prepared, it could unsettle the bike when you are at your most vulnerable (leaning in at low speed). It's not necessarily uncontrollable, just unnerving when you're expecting a smooth power delivery.
FWIW, my Triumph had the same issue, as did my KTM... both were remedied by negating the air injection.
