I will have to take a look at my bike and see if I notice something. If it the wires I am thinking, oil would have to be dripping on them from somewhere as they go from the coils down to the points housing.
1 trick is to clean the bike good, some simple green and a spray down. Let dry and puff on some baby powder or something like that and see if it sticks somewhere. It could easily be one of the 2 oil lines.
If you can, maybe a pic of the line in question.
The ride IS the adventure. The destination is just to get gas!
