I am tearing down my xr650r. And would like to know what kind of stuff should I do to it. I just removed all the coolant, and im going to put in some new one. Should I change the fork oil? I have done this before, as it was recommended. For some reason, I think my bike appears to be leaking oil, from the top of the motor. I cannot figure out why. All the wires are oily. And the front top left part is covered in oil. I noticed that my left header was loose, so I tightened it. Does this cause the bike to leak oil? Changing the sparkplug. Would ike to do a valve adjustment, does anyone have a website for how to do it to the xr650r. Im not sure I have the right tools, I have a feeler gauge, but what else do I need? What other stuff do you guys do?
