hello out there in gw land. i am about to change the coils on my 75 wing and it says take top bolt off the right side and the lower bolt on the left side. i took out air cleaner and the way is clear except can't see the lower left bolt. also there is a (looks like) ceramic piece with a large resistor attached to it. i do have a dyna 3 electronic ign. is that anything to worry about and is there an easy way to get coils out? :?:
