I just recently purchased a brand new 2007 XR650L. In 2 weeks i have put 500 miles on it. I have Desmogged Desnorkled Dj kit & a 55 pilot Ground the welds in the header I am going to wait a bit before i put a nice slip on, on it. I was kinda wanting to know what oil, and filters you guys use, and also what you think I should use for the first couple of oil changes. Like if i should use synthetic or not. I am already seeing a good deal of wear on the stock Trailwing that came on it. I have seen alot of people talk about running the Mt21, and D606. Has anyone tried that Michelin Baja racing/cross country tire? Anyway enough questions, i have found from reading posts you are all nice and very knowledgable, Thanks so much.
