Moin Moin HD FLS Heritage Softail BJ 2006 Who can tell me how hard you have to attach the two screws to the upper fork bridge ( handlebars). After a ride over our roads in northern Germany I could turn these by hand. That gave me to think. Are these the upper spring legs screwing? Or is that just a cover, so it looks better. Didn’t want to take this off completely. Don’t know what comes up to me. How much Nm do these have to be tightened. MfG Ap atura
