              there's a big Allen key in the Yamaha toolkit that doesn't appear to fit anything. .?

         The big Allen key is for adjusting the fork preload on pre-2012 bikes. It is a mystery why Yamaha still include it in the tool kit on the later models with raised screw and locknut adjusters? You don't need it, so increase your power to weight ratio by leaving it in the garage!
