It took me quite a while of slowly building up to trusting full power in 2nd leaned over, a lot. What really got me pushing was chasing my buddy, who races liter bikes (and has won every race he's entered this year) while he was on his fireblade. Always a game of " keep him in sight even if I can't keep up". On corner exit I always gained a bunch of ground, braking I'd lose a little ground and mid corner he's pulling away as expected. Mind you I'm riding at 100% effort, he's probably at 80...
That's when and how I figured out how to back in the rocket into a corner. It's not something I go out and plan to do, it just happens as a factor of riding hard enough for it to occur.
Charge a turn in marker at the top of 3rd, feed in front brake to threshold, blip, drop to second and the rear will start wiggling hard, which you can guide outward and finally as you reach the marker release the front quick but not abrupt and throw it into the turn, roll on quick but not abrupt starting at the Apex and by the 3/4 mark of the turn reach the throttle stop. Shift to 3rd just as you're coming straight up and down and moving your butt back in the saddle. At this point you'll be reeling in bike lengths very quickly.
It's the most rewarding, difficult, and mentally intense thing I've ever done on a bike along a 5 mile stretch of "the dragon" style curves on Mufasa. I'll usually only do a run or two as it's SO easy to over do it, and the bikes literally at it's limit (and so am I).
God I miss my bike right now... Lmao.
