The bike has to be level to check the oil (not leaning on the kickstand). With the 900 I can lay on the ground and push the bike up to level (careful not to push it too far!), I don't know how easy this is with a 1600. You can get one of those extending mirrors and sit on the bike and check it with the mirror. Or get someone to help you.
My biggest fear is when I die, my wife will sell all my guitars for what I told her I paid for them.
