My pulley bearings all have play after 8000kms (belt tension was checked throughout). I'm pretty sure I saw someone else with the same problems. It looks like the bearing loose their grease and wear themselves out prematurely. I started to hear a knocking sound so I took the belt off to check. I'm so glad it wasn't coming from my motor though.
They appear to be generic 6203-2RS no-name bearings. I love the kit but the cost savings that KW made seems to be biting us in the behind.
Also, does anyone else hate the fasteners that KW supplied? They look like sh*t after a few years turning a rusty colour.

Sound like me 2 years ago. That pulley should come pre-installed with larger fasteners and loctite-red.
