One of the pulleys is undersized or near the minimum limit for that drive belt. I don't see delamination I see compression blow out. Something like a Gates XL belt addresses that issue. A high durometer belt exacerbates the problem. 1/2" belt you want a 5" or greater diameter pulley. Guess we will find out if the Aramid makes a difference. It should have better heat resistance so I expect an improvement.
That belt routing is a crazy one 😮
For a Kawasaki it has been running very rich. In my experience I can see the insulator on Kawasaki's and Honda's.
