so my '07 wr450F seems to have a tight rear brake. basically the pads are right on the disk and this seems to always present some drag. on the stand when I spin the wheel I can hear a sliding sound and the wheel doesn't free spin for long. shouldn't the there be more significant gap? how can I adjust so this drag is removed? I have seen other bikes where the rear wheel will free spin really fast and easy, like a bicycle, thus indicating much less drag. I have moved around a lot recently and cant find the hard copy manual to even start looking there. with only 4 forum options for Dirt Bikes , hope this is in the best place.
