2008 Ninja 250 Dyno Area P stock jetting

This was directly after installing the new Area P full system. The bike produced 26.5HP stock and 28HP with Area P system. Jet kit will be installed this week. Ron Hopkins at RPM is the tuner and his phone number is 503-650-9401. The bike has 60 miles on it. Notice in the screen shot it shows the jetting super lean under 6K and then goes pretty rich thereafter. We did not have the RPM sensor hooked up, but on the previous runs we did and it follows the same curve. The pipe helps it, but not that much. Plus we are in Oregon and we have ethanol 10% blend which exacerbates that. Jet kit should help that out.

@ - Suavestmanalive - Dude you are very ignorant....i said a ZX2R has a 4 Cylinder engine NOT THE NINJA 250R !!!!! OH GOD !!!

[Suavestmanalive]

@D61664 no the 250r is not a 4 cylinder. Is it a four-stroke, 2 cylinder engine

[JCarapezza]

@D61664 the new ones have about 27ps at the wheel 33ps at the motor i have one two but it doesnt take much to get it to 33hp :)

CBR250rr had a 4 cylinder engine while the ninja 250 is 2 cyclinder.

I've got an Aprilia RS125 with a 154cc big bore kit and it produces 34bhp (check my vid for mods). I don't understand how the Ninja 250r only produces 28 tuned? Compare it to a cbr250rr back in the day with what 45hp...you must be able to get more horse from that motor but the highest I've seen is 30...odd/
