Look my rotors are warpped and I have no money to buy new ones. So I have been trying to fix the ones I have. They only have 9k on them so they are in good shape. Here is my Idea... Take the rotors off the bike and heat them in an oven or a kiln and get them up to 450-500 degrees for say 8 to 10 hours or so and see if they strighten. Maybe hotter than that but i'm just guessing! Any one have any input on this! Let me know what you think... I figure it can't hert them any more than thay are. How do they get these things stright in the first place?
