I have an 08 ninja 250. I did the air box removal and replaced with a kn r0990 filter pod with pod sock. Jetted carbs with 112. Used 2 needle shims. Bench synced carbs. Adjusted idle. I have done all new fluids, fuses, hoses, new carb, yoshimura slipon exhaust

Bike has to turn about five times or so before starting up then in every gear it runs to 7,000-8,000 RPMs tops. Max speed was about 57 mph
Factory I ran 100mph give or take and could redline. Now I can't redline at all while in gear

Someone said something about drilling out the fuel mix screws on the bottom and adjust those. Any info or direction would help. Thanks
