I did mine like this......" get front wheel up off the ground , take all the gauges and crap off to get at the lock nut, loosen the lock nut , tighten the tension nut up as far as possible finger tight , use a flat head screwdriver and rubber mallet and each time you tighten the nut 1/8th flick the front wheel left and right , ideally you want the tension where it hits the stop and bounces back to the dead center , once you have it doing that tighten lock nut and put all the other crud back on.
