Stage 1 jet kit for a 2008?
Surprised to find DynoJet doesn't appear to offer a jet kit for the 2008-10 Ninja 250, only a stage two kit. What is everyone using?
Just picked this bike up, has sat for a full four years and the gas was disgusting and carbs were pretty dirty. While in there I figured I would install a stage one kit to compensate for the (I assume) terrible factory jetting. I plan to leave this bike 100% stock otherwise. Carbs were a little tricky to get off so I just assume do it once. Any help is much appreciated- Fissel |

Each person has his own definition of what "stage 1" means. What is your goal? I'd do a thorough carb cleaning and run it enough to find out if it really needs any changes. My pregen runs pretty darned well stock, and gets mid-upper 60s for MPG. I have no plans to mess with that.
Welcome to the board, it's good to meet you. |

You saying the stock setup "runs pretty darned well" gives me hope. Do most people with the stock exhaust/airbox run stock jetting? Again, Kawasaki didn't make it easy to get the carbs off so I just assume not have to do this again anytime soon. |

I believe the stock main and pilot for the new gens are 98 and 38 respectively. I have the typical bolts on and only have 100 mains and 40 pilots. I'm actually thinking about going back to 38 pilots.
Every bike is different but I figured if I have all these mods and have only moved up 1 main jet size and 1 pilot size you may run to rich if you mess with the jetting. Have you tried adding some small washers to the carb needles? That helps with flat spots in the higher revs (7.5k-12.5k) *disclaimer: my bike could very well be running lean but the way she runs and the color of the plugs says shes okay* just figured I'd throw my .02 in for reference. Best of luck! |

Stock its lean at idle/mid range and rich on top end. Biggest improvement for street riding is adjusting idle mixture. If you rev the piss out of it regularly, maybe go down a size on the mainjet.

Oopss - i meant biggest improvement for street riding is adjusting idle mixture, not so much the needles. It transforms it from being anemic off idle to actually having a little pep. If you need to throw a washer under the needles to tune the midrange you can do that later with the carbs still on the bike.

Don't overlook the airbox-battery box separation mod. I love the improvements it gives.

Revving the piss out of it is what gets it off! The party starts around 9,000 RPM in the Ninja.

LMFAO!! So true... It doesnt have much torque but it has rpm and they will take the abuse almost submissively like "go ahead beat on me, it turns me on".

It's not really much abuse when the little pistons only move about 1-5/8 inches.

As an engineering boss I once had use to say, "harmonic motion." There are no sudden stops because of harmonic motion.
