Hi guys, quick question, a friend of mine has a K8 750 and he has lost his manual. He needs to know about the oil window and where the level should be when it's full. Also does the bike have to be straight up or can it be on the kickstand? He said when it's on the stand it's about mid window and when it's straight the window is completely covered. Does he have the right amount of oil or too much? Thanks everyone in advance.
