K100virgin, what year K100 are you riding? If it has a paralever rear it could also be the pivot bearings causing the play. The FD bearing will not 'fail' overnight but gradually wear over thousands of miles/kilometers. A new bearing will totally illuminate any movement. You can check the FD bearing for wear by using a screwdriver as a stethoscope, placing the tip on the FD and the handle to your ear and spinning the rear wheel. If the FD bearing is worn you will pick up a rumbling sound. Alternatively, if you have a paralever place the screwdriver tip on the pivot bearing lock nut and get a second person to rock the rear wheel at 9.00/3.00 o'clock. If the pivots are worn or in need of re torquing, you will pick this up as a noticeable ticking sound through the screwdriver. Often when it is thought the pivots are worn, sometimes a re torque is all they need. BMW suggest 8Nm from memory, but 10 is better. When torquing mine I torque them a couple of times to 12Nm to expel excess grease before a final torque to 10Nm
