I have a 2007 ninja 500. My bike has recently started bogging ( i suppose ) around 2-4k rpms and then when it passed 4500 rpms it’ll rip like it is usually does. I cleaned the carbs throughly and put a new k&n air filter in it. I’ve found a way to manipulate it though. When i adjusted the throttle control knob so it idles around 3k if i rev it past 6k rpms BUT if i just rev it a little to like 3500-4000 rpms it will drop down and idle at around 1k rpms. Anyone got a solution for me?
