Its heat cycles your after, do a few short hops, don't hammer it for maybe 50 miles, then stay off the red line for another 100 as on a new bike your running everything in so there 'could' be a manufacturing issue ( maybe an assembler left his lunch in the rocker cover). If nothing has fell of by 150 miles ride normally. A good guide would be to stick religiously to the posted speed limits for a few days and then let your caveman out gradual and you will be fine.
You can also ring its neck from day one, either works to be honest, any issues will affect somebody 5 years down the road when their 20k miles bike needs a set of rings.
Yes I'm being serious, you can run in or not. Modern bikes don't really need it, its how long you want/need it to last. Honda fireblades thrashed from the word go were shown to have more power than lovingly run in models.
I suppose you need to ask yourself, how much do you value the warranty because I guarantee the bikes computer will tell Yamaha if you tried to be valentino in the first 20 miles. Your question implies your already bored, Yamaha told you how far to run it in and you want to know how long it will take till you can spank it.
