Here are some pics of my plugs before and after the bump. The pics with 2 plugs is before the bump and the single plug is after the bump. I put about 100 pretty hard miles on it after the bump. My concern is the dark spot on the side of the plug. Why would the plug burn like that. The bike has 2000 miles on it and I am the only owner and the only performance/engine mod is a V & Hpropipe. I bumped the ECU 3 points on both cylinders. The current readings are Co 01 3 Co 02 0. Any info on the plugs will be greatly appreciated. The pics are in my gallery I am trying to get them here but until then here it is.
