Mines is starting to squeal so reckon its time for adjustment which goin by my scribblings in the back of the manual where I write down everything that I do to the GS ,last time I replaced the hall sensor about 6k ago .only thing its a fekin pain taking off the hepco becker crash bars and refitting them ,takes longer to do that than adjust the belt ... any other folk with the crash bars fitted came up with an easier way instead removing the bars everytime to do a 5 min job ? cheers
