Replaced stock coils with Dyna 5 ohm coils (DC8-1) & Dyna copper core wires with NGK 5k ohm caps to complete my ignition upgrade... Pamco was installed about a month ago. Hoping this corrects my weak spark on #4 so we can burn out some of the carbon buildup. If this doesn't fix my #4 issue, I'm probably looking at a top end refresh. Ugh! Hope to test run later today, then if weather cooperates..... get out for a long, spirited ride this weekend.... then park it for the winter.
