Ok, I'm almost done putting my bike back together after a complete tear down. I've got 3 hoses (and their replacements), and 3 spots to put them (that i can see and remember). 1. back center of valve cover. 2. top inside of oil can. 3. rear center of crankcase. Are all three of these just breather/drain hoses? Or is there a connection or something i'm missing?
