The photos I've seen of the FZ07 engine show a non-standard sprocket on the exhaust camshaft.
Now the parts diagrams for the 07 are available on the Yamaha site.

2015, FZ07, "Camshaft Chain" diagram
Maybe those small pins (Tag #11) extend out of the cam lobes until the engine is started and idling.
Also on the "Intake 2" diagram something else I haven't seen before -- a tiny stepping motor (Tag #5).
Maybe this provides the cold start elevated rpm and also the idle speed control from the computer.
Yamaha is always advancing the ball down the field.
