Ok this is an older thread but I wanted to keep the spark plug thread clutter to a minimum.
I've read many different posts/ideas on the ngk iridium spark plug gapping, do it or don't do it. Some say you don't have to, some say to do it. Now that iridiums have been run in Buells for several years now, is there a general consensus that you do OR do not have to gap NGK iridium plugs.
Some posts say they come pre-gapped, but mine are not .035, more like .025. Part number DCPR9EIX, 2316.
