WOW! Now that's a BUMP!
Humming seems normal? The valve train is all hydrolic so it should not be out of adjustment. If it was, you would see it at normal idle and not just at a higher rpm!
You can always ask a fellow stranger that you happent to roll up on that has the same year model as you!!! Owners tend to be cool about talking about their rides!
