brake rotors was created by Indymick
ok now that i have my swingarm bearings taken care of. My next question is about the brake rotors they seem to be strait (no vibration) but the have very very fine groves basic wear I think and discoloration. I took them to a race shop to see what they could do. They are road worthy just dont look as nice as they could. Any help!!!!!1:unsure:

It's almost impossible keeping brake rotors from getting grooves cut into them. The act of braking along with the normal grit,dust and other polution in the air and being close to the ground soon turns the pristine disk surface grooved and scarred.
Short of having them turned (and possibly be too thin)I'd get a new set of pads/pucks and go riding.

I sent mine to a shop in Portland that grinds them to perfection on a surface grinder. most car brake machines cant do these rotors.
give this guy a shout for 50 bucks you will not be disappointed

Unless a rotor is deeply scored or warped, no reason to cut on them. Fine lines don't hurt anything.

+1 When you need to resurface rotors, do not skim them on a brake lathe, but take them to an engine machine shop and refinish them on a flywheel refacer, making sure the thickness stays uniform. It takes off only a few thousandths, 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. The minimum rotor thickness will be found in your service manual, or stamped on the rotor. Worked great on my bikes and Corvette too.
