Help I purchased a 2000 XR650R and have been riding it for about a month. It seemed to have an appetite for oil but I went out tonight and when I came back there was oil on the back tire on teh change side and dripping off swingarm. OK so where do I start and what are the most likely culprit? This is my first XR650R, I was hoping for a summer of fun. Any suggestions would be greatly appreciated.
