I have no spark.I have a 1985 lt250r.I traced it down to the coil not getting power.The wire that goes to the coil has no power.It comes from the cdi box.Any help would be greatly appreciated.Thank you

 

check and clean all ur grounds, then if that dosnt do it pull ur fly wheel off and clean ur pick up off, the little black piece of plastic with the metal dot in the middle. I just had to do it to mine not that long ago, i also put electrical grease on everything !!
