Hey...I obviously have a water leak that's causing my crankcase oil to turn milky white. I'm assuming it has to be my water pump shaft seal that's leaking. Anyone have any experience replacing the seal behind the plastic impeller? Oh yeah...it's a 2001 Beta Rev 270. Bike runs great...no other issues that I can think of...plenty of power so I know it can't be a leaky cylinder base gasket.
