Are you sure it isn't main bearings?
If Kawasaki can't diagnose it, find someone who can and send Kawasaki the bill after you do find something. If you did find something, then they owe you the bill paid, in time of course.
Hopefully, you have in WRITING where the 2 Kawasaki dealers said it was normal noises. Verbal is nothing and it never happened. If you go back again, have them note that they looked at it and the date when. Get your ducks in a row: you are dealing oem dealers and oem musical chairs - they are pretty cheesy.
You are not going to get anything on a forum though. First you need a professional mechanic. And once you find something, oem knows they will also have to foot the lawyers bill if they are wrong. O/w, you are just amusement for the dealers past time. They are not going to give you ANYTHING because they owe you. You are going to have to MAKE them give it to you. 1. a mechanic will show they are wrong. 2. a lawyer gets respect real quick (good hungry lawyers are around - try Persian lawyers, they kick a$$.) If you don't have enough for the mechanic, tough luck: start your mechanical learning curve on a new bike (that already has a warranty.)
