is the R6 08 rear master cylinder a common problem?
mine feels like its a switch ... it's either on an locks up rear wheel, or it's off. Nothing in between

This can caused by some aftermarket rearsets (eg Vortex), when the angle of the piston is not dead-straight into the master cylinder. When you press the lever, does the piston move into the m/c exactly evenly, or on an angle?
