I was having coolant leaking into my oil through the waterpump seal on my '02 KTM 640 Adv. Using the handy guide at http://www.advrider.com/forums/showthread.php?p=2599155#post2599155 I rebuilt the pump with new seals, resealed the vale cover and top exhaust bolt. Waited 48 hours. Tonight is the first fire up. Holding thumbs that I (a) diagnosed the right problem (b) fixed it right. There's a lot of viscous white mayonnaise-looking contaminated oil - it's pretty sticky. What's a good way to flush out the oil system? Don't want to use one of those auto engine flush products - prob no good for the clutch, etc. Was thinking to fire it up (please, please start...) and let it warm up, check for leaks, etc, then drain the oil, and refill with fresh. Then ride for a couple hours to get it good and hot (which will hopefully drive some of the moisture out), and then do a full oil and filter change. Any advice?
