36mm fork identification. Help please

Hi , and thanks for taking time to read this thread.

I am trying to identify these forks. I believe they are possibly from a kawasaki KZ650 but not sure.
The inside of the fork lowers are stamped K723L and K723R there is also another cast in number above this.

Im hoping to find a new or clean set of Stanchions to replace my ones due to some light pitting.

Any help would be appreciated.

thankyou all in advance

Could be 650, but others would know better.
I can say you can rule out 550 for sure.
