1995 Kawasaki Bayou 400 4x4-Two years ago this problem started, the engine would not fire, but you could wiggle the wires in the back and it would start. Progressively has gotten worse starting until now there is no fire at the plug. Have checked all electrical compotents at the rear of the Atv by placing them on a similar ATV and they all work. The coil and cdi work. The wiring seems to be good as far as I can tell, and suggestions? I have looked at the schematics on the Kawasaki site, but they appear to jump around and have no logical flow so I can follow them from one area to the next. I have been looking for a used Kawasaki shop manual used, but no luck there. Does anyone have a used one for sale? Can anyone suggest what I should try next?
