I apologize if I missed a post on this. This is my 1st Harley it is a 98 Softtail Heritage Classic. I just discovered my cam sensor has a large melted spot where the wires run in to the magnet. Will this or could this cause a spark knock. Bike just started running like you know what. Plugs are showing way too rich like out of time or weak spark. I changed them & the new ones carboned up rich almost immediately.
