im thinking about goin -1 in the front and +2 in the back on my 929. where does the speedometer get its reading from?? some people say the sprocket, front wheel,rear wheel,chain etc. i had a 600rr and my speedo was off by 5mph at 55mph because of this. i know a speedohealer will fix the issue. i dont want to buy one though.
