Off the shelf pipe/ jet kits can get the Ninja 250 to 30hp. 26hp of the stock engine can already take it to 7 seconds 0-60mph and 14s for the quarter mile. Plenty fast unless you just want to do wheelies. The peak power of the new gen and old gen are almost the same. The new gen cams are supposed to offer a better midrange but the power is still very much toward the top compared to my CBR250R. The nice thing about FI would be to get consistent performance regardless of weather and altitude when traveling and improve the fuel economy while doing it. A jet kit on that bike takes the FE right to the low 40s mpg range.
