I got a 2007 400ex with a stage 1 hotcam k&n air filter with prefilter, stage two jet, and a full curtis sparks exhaust. The other day i was goin pretty fast (almost topped out) down the road and i let off the gas to slow down it crackled a couple of times then the engine stalled. It almost sounds as if its running out of gas. Im thinking its running to lean but any other opinions would be appreciated. thanks
