I previously talked about the Dynojet 2193 Jet Kit for the Kawasaki Ninja 250R a few weeks back (Link Here) and since then I have installed one had one installed and all I can say is… Wowzers!!!

Review

So, um, why exactly does the bike not come like this stock? This upgrade is night and day compared to the stock needle settings.

The bike comes from the factory jetted to meet emissions standards. Which is why I need to say the following:

“The DynoJet Kit is for Offroad use only… yadda-yadda.. Installing it might also affect your Manufacture warranty from Kawasaki… yadda - yadda.. Install at your own risk, and remember the polar ice caps are melting before you mess with emissions equipment…”

In the stock configuration, the Ninja 250R is very anemic in the low RPM range. So much so that below 5000RPM’s in first gear the engine bogs way down.. Almost as if it’s geared too tall (which we all know is NOT the case). And over 10,000 RPM’s Power drop off is drastic — Making the usable power range in stock form really only like 6k - 10k RPM range. That makes sense, since those are the RPM’s you traditionally find yourself while your cruising.

This kit comes with all the jets needed for Stock Upgrade to Aftermarket Exhausts and Intakes. So once you buy this kit, it can grow and adapt to any aftermarket upgrades you add in the future.

After installing the DynoJet Kit — Usable RPM’s change to the 3k - 12k range. The bike just comes alive and the power band smooths out making constant gear changes to keep the bike in the 6-10k range much less frequent. First gear riding when the bike is cold becomes much less unpredictable and scary, and once the bike is warm you’ll find the rev limiter quickly because the bike keeps pulling well all the way to red line.. You no longer have the noticeable drop in power to remind you to shift.

If you have been on the fence about installing this kit. Don’t walk — Run — to the nearest dealer or Dynojets website to pick one of these up.

It’s rumored that the 250R runs a little lean down low in the stock form. Once people start to pull airboxes or start adding exhausts to the mix you start to run the risk of really leaning out your engine — Which will end badly..

There are a few shim mods you can do to your fuel jets to help with fatten up the mixture (that’s another day) — or for about $80 you can pick up one of these nice little kits from DynoJet.

The Kit includes 4 sets of jets, titanium fuel needles, and a few other bells and whistles needed to get the job done. With the Stock DJ096 jets and a stock Airbox the Dyno Charts show a smooth increase in power from about 5,000 RPM’s to 9,000 RPM’s (Almost 2HP) With the real gain coming after the sharp 10,500 RPM to redline drop off the stock bike has.
