Let'Roll, most machine shops will do it. I've had several skimmed. It is expensive.

If you get them done have the outside peripheral skimmed as well, purely for aesthetics. Also a slight chamfer (just to break the sharp edge).

For those with Z1 series (maybe others). You may think you have caught a stone or something in the caliper to a gouge a groove in the rotor. Have a check of one of the caliper retaining bolt, it is probably just prodruding, enought to scar the surface.

The local bike shops around here that will do it charge about $50 and new rotors cost $80 on up so it's probably more feasable to buy a new rotor unless you're really on a tight budget or you can get it done much cheaper...

Instead of turning rotors on a brake lathe I've had excellent success having them resurfaced. Take them to an engine machine shop and ask them to re-finish them on a flywheel refacer, making sure the thickness stays uniform. It takes off only a few thou of material, leaving a nicer finish without chattering, eliminates the phonograph record groove effect, takes out the hard spots better, and gives you really smoooooooth braking for about $20 - $30 a rotor :)
