I think those two links should answer your questions Beerkat. I think the M25 is the thread size on the inside of the new nut and it is the same dimensions as the original chrome nut and so the 1 1/2" socket fits both.

This is where I copied the idea from...


The torque figures he mentions are correct I think, well, the same as I'd seen listed elsewhere from a copy of a Haynes manual.

 

I've just looked out the Service record card. I'm still around 70kg, not sure what my helmet and leathers weigh on top of that. I think I said I'd have an occaisional pillion of similar or less weight and mainly riding sensibly/quickly on the road. I have been around Thruxton since though.
The rear spring rate is 16-24 N/mm according to the card for the NTR-R3 twin shocks. I've been tweeking the rebound and Hi/Low compression since and pretty happy with it now. I've changed the preload too to set up sag etc and it is easily changed for a pillion too. And the forks have a spring rate of 9 N/mm. I've no idea how that compares to stock. Again, I've got adjustment for preload, compression and rebound and have been tweeking those +/- from the base settings Nitron gave me.

I highly recommend them for their service and quality of the shocks/forks. Better than Ohlins in my opinion.

Also fitted the Triumph fork brace.

 

The fork brace compresses the rubber boots a bit and I tried the fork alignment check too. All seems well and I've never really suffered brake squeal. Thanks for the suggestion.

 

My rear preload is 21mm, measured in the same place, the threaded section basically. It wasn't written on the service card but I've kept a little notebook of all the settings I've tried. I've measured for sag etc, but my principle guide has been to put a small cable tie on a damper shaft and check that it doesn't go too close to the bump stop during normal riding and it gives you a quick way of seeing how much of the available travel you are using. I stiffened it up by adding 5mm (26mm) to that for a 60kg? pillion which seemed to be about right.

The settings I was given as a base point was -14 for rebound (screw it all the way in and then back it out 14 clicks), -12 for Hi Compression and -8 for Low Compression. I always use the method of counting the clicks out from full hard (or screwed in all the way).
I'm currently on -15 rebound (out of a possible 24 clicks), -11 hi speed and -8 low speed (which both have 16 clicks available).

If you have the same Nitrons as me, I'm sure you know about the tiny plastic grub screw set into one of the holes in the adjuster ring. I bought a 3.0x50mm flat headed screwdriver for the job and you should have a tool to turn the ring when it's too stiff to turn by hand.
Hope that is what you need.
