I rebuilt my 2003 WR450's head, put new rings, put a TrailTech Stator, and put in a new Timing chain. All 45 Hours ago. Did Oil changes with filter change every 20 Hours with the two first being Lucas Oil, and I put Amsoil 10w40 synthetic in it for the last 4-5 hours. But it started making a weird noise that I hear from the clutch cover area. Any guesses before I tear it up?
