oil leak

[medicaldawg]

front cylinder left side. looking directly at the front cylinder it looks to be coming from some where around one of the spines that stick out. its not a major leak. I changed the oil two days ago and the oil looked like molasses ??? but did check oil level before changing and it was full of oil. My uncle owned the bike about a year before me and never rode it , but i did . He never added any oil but neither did i. so its obviously a very slow leak. havent really got down and looked to see where its coming from just looking for some sugesstions on where to start.
