Over the last 2 months I have been working through issues with my new to me 03 640. This is a new one. Yesterday my bike was getting pretty hot just riding around town. Hotter than ever before and it wasn't hot outside. So when I got home I started hunting. First off it was low on coolant. I don't know where it went. It was about 2 cups of coolant to top it off. Second thing is the oil in my site glass was too high. Actually past where I could even see the oil line. It has been about 1000 miles since my last oil change. I have watched the oil level rise slightly over the last week or 2 in the window. It happened so slow I wasn't sure if I was imagining it or not. But sure as hell I sucked 175ccs of oil out of the engine to get it back down to the high mark. The oil was opaque but not black or milky looking and it didn't smell gassy. But I guess it could still be gas. If it was water there would be mayo looking funk on my oil filler cap and the oil would look milky right? Or does full sythetic oil emulsify water really well and suspend it in the oil? It did take more coolant to fill the radiator than what I sucked out of the engine to get it back to the correct level. Is it possible that I filled the oil wrong in the first place? Should the bike be hot or cold when filling to the high mark on the glass? I did it when cold after I bled the tube. So the question is where did this oil come from/ or what got in the oil to increase it's level? I am going to install a coolant catch bottle to see if that fixes my disappearing coolant problem.
