Recently got my YZ250 and so far I really like it. One thing I am having a problem with is the front brake. It seems to have lots of "play" compared to other bikes and worse yet while riding and using the brake you can feel it pulse- almost like the rotor is warped(its not). In trying to troubleshoot it(while stationary) I get a solid amount of pressure until a certain spot in the disc and then the lever goes to the handlebar. Let out and it is nice and solid again when pulled. I have Braking rotors with brand new pads, new fluid, and stick caliper/master. Should I get new rotors? Could one part my rotor really be thinner than the rest?
