Okay I replaced the aluminum rod and resistor in the plug caps with brass rod and installed the NGK DR8ES-L plugs. Took it out for about a 15 minute ride and checked the plugs when I got back. The condition indicated that it is suddenly very lean. Before doing this I had in the standard NGK D8EA plugs and the condition was perfect. The plugs were a nice tan/brown. So is this normal to see when doing this mod? I made no other changes. So i'm slowly adjusting the needles to try to get that brown/tan color back in the plugs. Just wondering if this is something that should be expected.
