I have a 90 cc panterra atv with very little spark. I have replaced the entire wiring harness including the cdi box, coil, starter relay, plug, ignition switch, and the full stator assembly. I have had this running before but all of a sudden when you try to ride it, it just dies out. Now I cannot get it started. When I pull the plug out to check spark it is very little and spurratic.
I would appreciate any advice on what to do next.

Thank you

Is the spark plug stock? You should try a NGK spark plug... I hear that the ones that come in chinese quads suck. Just my 2 cents. [img]i/expressions/face-icon-small-wink.gif[/img]
