I have an 03 CBR 600RR and got an oil change about two weeks ago and had a new tire put on a couple days ago. Since the oil change I have noticed an odd smell coming from the bike like burning oil. Tonight sitting at a light I noticed smoke coming from the bike and upon inspection there seems to be some residual oil around the filter and on the headers. I assume this is what it causing the smoke? If so is there any reason for concern? Also while I noticed that I decided to check the oil levels through the glass and the level seems to be fine but the color looks just as dark as it did before I had the oil changed. Should I be concerned about this?
