Can someone please help me with my assumption about jetting. I am fairly technically challenged in this area. I have an 06 yz450 with all stock jetting and live in the tampa, florida area where we have real high humidity and of course high temps. I have read that the bike will run rich since there is less oxygen in the air from the humidity. So my question is - is my assumption correct? Can I just lean out the jetting a little by raising my needle clip position and adjusting the air pilot screw? I am looking for the jetting for dummies 101 tips here. My symptoms from the bike are a slight popping when backing off the throttle... not back firing just a pop - pop sound. Thanks!!
