My GPZ 1100 annoys me – I had already described it elsewhere – with a strongly pulsating front brake and a still overflowing carburetor 2. The latter is not a bigger problem, just a fiddle, on which I am actually not so sharp, but the brake annoys. Often enough a offset of the discs to solve the problem (or just to create) but if the disc has a blow away, you have to replace it or have it straightened. Now I would like to test this. . By having to get the wheel out for the new front tire anyway, I would unscrew the windows and check them. Has anyone ever done this ? Put on a glass plate ? Put anything on it before ?
