06 450r bogging

[450r729]

dose anyone know why the 450r has a bad chop bog? i am having problems with mine stalling out when i go off jumps.
i have an HMF ironman exhaust and a k&n air filter which i cant use because it makes my problem worse.

do an HRC kit with your k&n and exhaust. Your bike will run a lot better and the kit comes with a lot bigger jet. youll be set!!!!!

than play with your air/fuel screw on the carb..
