You should've put money down. The bike is going up for sale today.
The final straw was doing a trackday on it. Yes, it's not a "true" sportbike, and shouldn't be expected to haul-ass on a track. I didn't expect it to. But I at least expected it to be enjoyable.
Those throttle shortcoming became painfully obvious on the track. One turn in particular, every single time I went into it, the throttle lagged. I'd brake into it, roll on...wait...keep rolling...keep waiting...wait some more...then WHAM, now it actually accelerates. And now I'm completely off-line since I expected power sooner.
The fact that I keep asking myself if I should get a different bike is confirmation enough that I should.
