My bike bogs off idel when i rev it quick...rich or lean? its a 2005 250SX. I have mess with the air screw a and it doesnt fix the problem. Right now my jetting is 170 main, 42 PJ, JD Blue middle clip, AS 1 turn out, and running 44:1 Ridline oil. I am riding at 300-500 feet above sea level. What do you guys think will fix the problem?
