OK so here's the deal. Went riding Sunday rode for probably 1.5 HRS with the quad running fine, and all of a sudden it started cutting out. It wont idle and all the way through the rpms it cuts out. I came home and cleaned the intake filter and the crankcase filter and it still did the same thing. Bad spark plug? I didnt totally trace any wire down but didnt see any apparent wires wore down. ANY MORE IDEAS TO EXPLORE? I have not pulled the plug. Its stock of an 08.
