I use Cyrul's WOT method. I mill a spare head down so it has only two or three fins remaining to keep temps up.
Up north in the winter you may need a heatgun, but down south or in the summer the milled head is enough to keep temps up to 180- 200F at WOT.

It's a good idea to mill an extra head but the problem is getting that extra head. Most people don't have an extra head for a new engine especially one as new as the Ninja.

7th tank 1/2 throttle
8th tank full throttle (make sure engine is running rich)
9th tank 1/2 throttle
10th tank 1/4 throttle
Put the engine in the car and run two or three tanks at a rich setting on the track and then it will be o.k to lean it out.

Sharing such tricks of the trade are a unique quality of a true professional. Hats off to you Mike.. 
One last question though if you don't mind. Do you mean blipping or holding it steady at 1/4, 1/2, and full throttle during the tanks you mentioned..??

Come on people, there are a few good break-in procedures, and all of them have the same result.....

I may be wrong, but I use to run 4 tanks at full throttle on the breaking in bench and it lasts about 45min.
