Ok I now see if I can get it right this time.
The nut I am talking about is the headstock nut the large chrome one in the center of the top triple tree.
I am sorry for all the confusion it's not the head bearings or steering stem nuts and from what I can figure out when the bike went into the dealership they just torqued up the headstock nut to load up the bearings.
I have now torqued the headstock nut to 65Nm so does this sound right and again thank you for your replies cheers.
