Just had the top yolk off again tonight to make small adjustment of the two locking nuts and cant quiet work out why after following workshop manual guidelines on tightening why they keep loosening up...... ? I ve done this same adjustment three times in last month..... and im off to IOM tomorrow..!
Do you tighten with weight on the front wheel? I always adjust headstock bearing preload with weight on the headstock, this makes sure that the bearing is not being pulled down by the weight of the shocks .
