Beginning my rebuild

Okay I need some more experienced opinions on this. From my pictures, how many hours do you think are on this bore? I have no idea and have no way of knowing.

Impossible to know how many hours on it but looks a bit of a mess, that chamfering is terrible, at first I thought it was sleeved but looks to be nicasil,

I am positive this is original, so this is how kawasaki shipped it

Hard to tell how many hours just by looking unfortunately. It could have been fewer than you may guess if the air filter was rarely cleaned, but it could be more than you might guess if it was taken great care of. Too many variables at play to make a safe assumption.
Definitely time to send it to get replated and maybe get that chamfering cleaned up as well, I'm surprised it came from the factory that way.
Good thing is that it will pretty much be like new once you send it to get replated.
