The copper tubing gaskets get most fully compressed. Some have aluminum gaskets for the same application, and they are a bit corrugated. Also check that old gaskets were removed first. I once pulled three old flattened out copper gaskets out of each port of a GoldWing head.

Whenever I've attached exhaust nuts I've always pretty much whaled on the them - you don't want to break anything but the copper gaskets are designed to compress under torque and make a good seal. If they're not compressed, you'll get a leak or a lost nut. Happened to me on an old bike, luckily a roadside fix got me home

The low speed pulsation of the OEM rotors was just getting worse. Both rotors were fu***d.

Waste of money those ebay rotors were. Wont be doing that again unless I can measure used rotors myself.

Bought a set of Arashi chinesium rotors and they are fantastic so far. Very smooth and controlled braking.

I was starting to think maybe it wasnt just the rotors but something uneven about the rotor adaptors underneath, but it isnt. It was just the old, beat up OEM rotors.

Theres about 1/4" of the rotor the pads arent grabbing. Gotta look into that. I'm guessing because the old uneven rotors bedded the pads unevenly. So will give it some time and see if they start to even out on the new rotor. They dont have very many miles on the pads so not sure.

I was sure old ones were removed. I think I was under the impression the copper gaskets werent meant to be fully crushed so I probably judt never had the nuts as tight as I should have.

Been ok for a few rides now that I snugged them all up more.
