YZ250F 02 250F snuff out

Recommended Posts

So I have an 02' YZ250F that I picked up yesterday for a song. The PO put a newer head on with the decomp cam to eliminate the cable. The bike fires right up and kinda idles. I have a 170 main, 45 pilot, 70 intermediate jet and needle on the 5th clip position like FMF recommends. FMF exhaust as well. New air filter too. I have the air screw turned out 2 1/4 turns. If you ease on the throttle it will snuff the motor out. It will rev when you blip the throttle. Haven't had a 4 poke since 2006 when I had a new KX450F. What am I missing in the carb tuning to get rid of the snuff out?
