Ok I try and explain on what I am trying to say.
The large nut in the centre of the top triple for the steering head bearing is there a torque pressure setting for that.
About two weeks ago I took my Speedmaster to my local dealer and asked if he could tighten up the steering head bearings because the bike has a bit of a front wheel wobble around 75kph with my hands off the bars on decel.
It only took him about ten minutes to do the job, it looks like he may of just over tighten this large nut which put pressure on the steering head bearing which made the bike weave from side to side with my hands off the bars and not to good to ride.
I just came home from my mates house and we worked on my bike, to loosen this nut we had to use a breaker bar and a lot of force on the socket wrench to move it.
Ok my mate had a torque wrench and we did tighten the nut not as much and now the bike feels a lot better to ride and does not weave from side to side anymore.
So is there a torque setting, have we done it right, before with the bike sitting on the jack the forks did not fall to the left and right without been pushed a bit but now we lossen this nut they seem to fall ok not to fast but they do fall by themselves.
Ok I hope you can understand what I am trying to say, I just felt that the dealer did overtighten this nut and like I said it seemed to follow all the lines in the road, but now it feels better so have my mate and myself have done the right thing cheers.

After the steering head bearings have been adjusted and the lock nut tightened. The top nut is torqued to 65 Nm.

Ok my mistake just to let you know it is the steering stem nut I am talking about the large chrome one in the center of the top triple tree so it's not the head bearing lock nut cheers.

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.

This is very close to the way ours work http://www.youtube.com/watch?v=CQHu3t-0QEAOf the three nuts in question, the bottom most adjusts the bearings. The middle (called a lock or jam) nut locks the bottom nut in place, and the top most nut holds the yoke in place. The top most nut does nothing to adjust bearings. The bottom and middle nuts are hidden from view when triple tree is fully assembled. If someone did indeed try to adjust the steering bearings by over tightening the top most nut, then a concerted effort should be made to keep this person away from all tools, vehicles of any sort, and other assorted sharp and pointy objects.

I am going to agree with your reply here I tell you what happened.
As I said nearly two weeks ago I booked my bike into the local Triumph dealership to get the head bearing checked, I stayed at the shop in the showroom when they took the bike to the workshop.
I was only in the showroom 10 maybe 15 minutes when they finished working on my bike and told my the head bearing have been tighten.
So I went for a ride and found the bike was not to good to ride and if I did let go of the bars the bike weaved from side to side.
I went back to the dealership and told them what was happening they told me not to worry about it because after a few weeks it would wear in and the bike would ride nomally of course this did not happen.
Ok I went to a mates house who is pretty handy working on bikes and asked him to check out my bike and see what he thought, after he took my bike for a test ride he came back and told me he thought the steering was to tight.
So here begins the fun, we put my bike up on his jack and found out there was no free fall of the forks to the left or right not a good sign, so the first thing we did was loosen the headstock nut (this is the one I was trying to find the info about) having to use a breaker bar on it because the nut was torqued up that tight.
As soon as this nut was loose the forks had free fall again, so here lies my tale of woe, the dealerships way of tighting and checking the head bearings was to overtorque the heasdstock nut so much that it loaded up the head bearings with pressue thus making my bike do the weave and not making it much fun to ride.
So now I got my bike back to handling the way it should thanks to all the helpful replies here and on another site about the right torque settings for the headstock nut, as for the dealership well they have lost my business which makes it harder for me, because the next closest Triumph dealership is three hours away but I cross that bridge when I come to it cheers.

Wow. That's altogether frightening. I'm glad you lived to tell us about it. I'm not sure how their ham handed gaff would have behaved at the far end of lean in chicken strip territory. Not so well I'm thinking. I hope they didn't bugger up your spindle threads.
I'm sure there are many great Triumph techs out there, but it's stories like this that have kept me from ever getting any dealer's service, not to mention it's usually $90 US an hour around here.
