Just installed new bearings in the steering head and put it all back together, but the nut at the top of the shaft when done up tight still has 4 threads showing ( i seem to remember the shaft being flush with the top of the nut.

At first try the nut would not grab at all so i gave the bottom of the shaft a few decent taps and got a few more millimetres of play. A second try yielded no more play, so i assume that's it.

Should the tree's flop from side to side with no resistance ?, or should there be some resistance?. At the moment there is some resistance but it's nice and smooth with no notches.

Can someone please measure their's from the top of the lower tree to the underside of the top tree.

Thanks
 
I checked in my shop manual. The dimension given is 182.5 mm or 7.184" from bottom edge of top triple to top of the lower one.
This is in the G5/1000sp manual, being the same frame it should also be aplicable to the LM. Somebody can chime in and confirm this.
 
I don't have anything here at the house to measure accurately.I'll get it tomorrow. The mesurement given is right at the steering stem.
 
I finally got this measured, I've got 226 mm. I have also taken a shitty picture of the top nut assembly.

Thanks for that, but it's sorted, it is correct that when the top nut is tight half the threads are still showing. You would think they would have made the shaft 10mm longer which in turn would make it a lot easier to seat the top bearing.
