Alright fella's I don't mean to beat a dead horse but I need some advice on how to read my plug. I'm runnin a complete FMF Ti4 system with there power up jet kit. I also have the Boyssen quick shot pump cover. I have it jetted to FMF's/Dynojet kit recomendations. I live in Tucson so I figure the jetting specs would be real close to FMF I pulled my plug out after a month of riding every week. It is really black,dark black but the very end of the electrode has a small white spot. Can't hardly notice it unless you look hard. I swapped it out with an Iridium plug and put one ride on it. When I pulled it out it was really black also, but the tip was clean. So whats goin on here, am I really rich? Whats up with the white tip???
