I have a 1994 KDX 200 with FMF Fatty pipe & Silencer, airbox lid removed, Boyneson Power Reed, Torque Ring, & frp Power ring. Jetting:155, 45, and air screw out 1/2. Running BR8ES Spark plug with 40:1. Clip in the middle position. I have to run my air screw at 1/2 turn out otherwise it starts reving and starts to lean out. I replaced all the gaskets aorund the carborator, reeds and valves. What's up?
