+1 to what Ian said. My '05 was exactly as Ian stated from the factory. Just tweaking the pilot screws to the same adj. made a huge diff. Also, before doing ANY carb tuning/jetting, it's imperative to learn HOW to jet the carbs. More is NOT always better. I've been using a K&N filter w/stock air box, #110 mains with Factory Pro adjustable needles, and 15-39 gearing for 2 years and still getting 62-67 MPG ( depends on riding style), and 100+ MPH on the Interstate.
I've wanted a 300 since they came out, but after hearing of lacking performance from new owners I'll keep and enjoy my 250 and watch for Ninja 300 performance enhancing info.
