my crf150f runs fine for a couple minutes then starts bogging out little by little. If I turn it off for about 5 minutes then try it again same thing, it will run fine for a couple minutes then bog out. tryed changing spark plug, and cleaned carb any ideas what could be wrong?i removed the airbox and installed a uni pop filter. Can that have something to do with it? Should those little foam pop filters be lubed?
