Ive been having issues with cylinder 4 misfiring and staying cold. I had the carbs rebuilt last month, but this problem has been happening since I installed a set of green dyna coils before the rebuild. I installed the copper wires/boots that were supplied with the dyna coils. I'm pretty sure they are not resistor caps. The plug cap on cylinder 4 shocks me when I go to pop it off while the bike is running. With this info my mechanic has told me this cylinder 4 issue is most likely related to a faulty plug cap. What would be the recommended NGK plug cap to replace the dyna caps with? From what I've read, it's a good idea to use resistor caps for this application. Correct me if I'm wrong!
thanks!
