So i bought a set of iridium NGK CR9EIX's. Gapped and installed them. My bike ran like shit. Bought a set of regular NGK CR10EK's and the bike ran well. I don't know what the problem was. Have they worked for anyone else?
So now I have a set of CR9EIX's with about 50 miles on them. If anyone wants to paypal me $5 for shipping, you can have them.
Really? You don't gap iridium plugs? I actually put them in once without gapping them and it ran like crap. Took them out, gapped them, and it still ran like crap.
I was always told not to gap them. Weird that they did not work for you either way though
