man, not me. Keep it stock for wife: reliabilty.

Normally, I'd be right there with you on stock=reliable, but these bikes have awful fueling (stock), which results in major flat spots in acceleration, and it can be frustrating having such a non-linear throttle.
The jet kit will only make it better, smoother, and less likely to stumble out of the gate, and will eliminate the mid-rev surging.
