Thanks for explaining. Here's the reason I brought it up. I have a very slight unrest in steering, between say 60 and 85km/h. I have checked everything and all is good. I have noticed that whenever I have (re)adjusted that bolt to spec, the unrest is gone.
It is not dangerous; with just one hand at the handlebar that slight unrest does not increase, let alone it develops into a tankslapper. Also there is no increase in the disk's temperature. It's a minor issue. I'll do some experimenting and will report back if removal of bolt and spring brings any improvement.
Head bearings…..or swingarm bearings….or tyres?
