2008 Kawasaki Ninja 250R with Yoshimura full Carbon Fiber Exhaust, jetted with DynoJet kit, and Intake Snorkel removed. *DJ100 Main Jets, Eclip on second pos, with one washer and spare eclip on each needle, mix screws each 2.5 turns out* Tuned a little rich, but runs excellent. **** By the way, don't yell at me for revving a cold bike... becuase It WAS NOT cold in the video, I had just gotten back from an hour long ride. :)
