650/X-2 Carb identification

[MarkP]

Can anyone tell me which carb this is? Dug it out of 650 box. I had an x2 and a 650 sx. Not sure which one it was from. Lost my micrometer or I would measure it. Only says cdk on side. Thanks

28 mm keihin. Needs a remote fuel pump. I believe they came stock on some Kawi 650s.
