Hi, i have been reading about iridium plugs and the recommended type seems to incorporate a resistor. As i understand it the standard plug caps are resistive. Does this mean that the plug caps should be changed as well as the plugs?
I have D8EA plugs in my bike but I tried DR8EAs as i couldnt get the D8EA locally and it didnt start or run well so i switched back. I assumed that this was because the doubling up of resistance weakened the spark. The resistance is only there to prevent interference on tv and radio anyway, as far as i know.
Any ideas?
