I've noticed that I'm smoking on the left side on deceleration plus a plume when I twist the throttle pretty hard. I pulled my plugs tonight to notice that my left plug is pretty black and crusty. I assume that this is burning oil from an issue with rings? I cannot think of anything else that could cause the issue. I'm gathering that I am looking down the barrel of a top end overhaul?
