My old rotors and brakes (OEM) did the same thing. I was hoping a different combination would help but not so much.
I didn't see why they couldn't be machined, if the shop goes slow but just curious if anyone else had experience with that.

It's the interrupted cut that makes machining them difficult. You need a certain hardness in the carbide to cut them and the interrupted cut breaks down the cutting edge.
I thin the rotors on Kawasaki Triples so the EX calipers can be used. Holes and slots cost extra due to additional cutting inserts consumed during machining.

.002 ( two thousandths ) of an inch variation in thickness creates a lot of feedback thru the lever.
I'll send a PM with my email address, I might be able to true it up if a replacement can't found.
