For the last week or so i've been noticing that the bike idles kinda rough at start up till its warmed up. I've adjusted the idle but it seems to have slipped back down a bit. Also, when a lil while after start up and idling someone smooth yet not all up to temp, i crack the throttle a bit and at times dark smoke comes outta the pipes and others its a bit white. I have D&D slip-ons installed. Am I runnin rich cause of the straight through design of the D&D's? If so, its off to buy a PCIII if I can find one cheap. Any help is appreciated brothers..............
