Problem with chain adjustment

[fazersharp]

I may be wrong, but I thought that the torque arm was supposed to pivot, otherwise it will bind and work against the suspension movement.

Based on this theory, you shouldn't have to loosen it to adjust the chain, however, when you find yourself in this scenario, remove, clean and lubricate the torque arm so that it moves properly.

  :agree I agree with this

The torque arm would only need to pivot if the front end is fixed to the frame, on the Fazer it attaches to the swingarm so doesn't need to allow for suspension movement.

That is also right - the pivoting of the arm and the rotating of the calaper comes into play when the wheel is moved back.
Look at the bolts - they are designed so that the thread ends before you can tighten up too much arnt they ?
