I have an 03 300ex full pipe, filter, no lid and has benn jetted. the quad idels,and runs perfect. I installed the jet kit just like the paper work says 3 turns out on the mixture screw. Heres my problem I pulled my plug and its black. If its running fine should I leave it . Its probably running rich will this hurt anythingand how do I lean it out I just turned the mixture screw in a half turn and it still idels fine havent opened it up yet?
