The sight glass can be deceiving on bikes if there is any tilt in any direction. But once you have it completely straight up and down while on flat ground, check to see if it is between the marks. Near the high side won't hurt, but when you get to the top line or above you can at the least expect some oil slapping and cavitation from the crankshaft. Best to lower it to a point between the marks.
