My Raptor lost spark after riding all day,with no problems.Tried messing with the ignition coil wire and then gained spark back.Started it up and then 10 seconds later the spark was gone.Tested the plug on another bike and is all ok.Could this be stater problems.Or bad ignition coil?

 

total guess...I say stator

my buddies 02' A/CAT 400 4x4 was doing this and turned out to be a $400 stator

 

Yea, I was afraid of that.You think that a stator could work once and not the next?
