Well, here's the plug from my 650L. Its a DPR8EA. The plug has thick black carbon(?) and the tip is a lil white-ish. I am running uncorked, Supertrapp muffler, twin air filter, 160/60 jetting. How does this plug look? It seems to me that it shows signs of being too rich and too lean. Or, is this just right? I am not having any running issues, I'm just curious. Let me know guys:applause: I am using CFN/Petit gas.
