I have been finding a drop of thick dark oil under my 2012 Street Triple r every morning. I've started putting a newspaper down. It is almost like grease and quite dark, so if it is oil, it has been mixed with road grime to make it dark cause the oil is new. It looks and feels like black grease. There is also some oil along the bottom of the engine, also very dark but not as thick as the stuff on the floor. Anyway, I have been oiling my chain after every ride and I suppose it is possible the oil is spinning off of the front sprocket and running down. Could that be it? I've stopped oiling the chain for now until I figure out what's going on. Engine oil level is fine. Thanks.
