When parts are not mated correctly, they will have premeture failure. Maybe not right a way, but they do fail. I have heard about the dyno break in method and the ride it like you stole it method and have fixed guys bikes who did these methods.
The bike comes with an owners manual and usually all the Kawasaki's I have seen usually require a 1k mile break in.
I recommend reading the owners manual and see how they say to break it in. I usually follow or just a very little bit harder than what they say for the break in period.
