Not understanding 500 front suspension 🤔

I'm certainly not using the old spacers - I'm in pause/thinking mode to decide if to return to standard or us a smaller spacer.
What thread is the shaft & nut supposed to be please it's an M8 but my M8 x1.25 dye is clearly the wrong pitch at first glance ?
I think it's M8 x 1.0 pitch??

If 10 threads measure 10mm then the pitch is 1.0. 👍

Never thought of that - I'm thinking to myself that counting threads might be harder than it sounds - I have a little thread gauge tool but I can never decide if the bit of metal is sitting in the threads properly or not. (Need to go to Specsavers)
Sounds daft but my method is trying a nut on a bolt of known pitch - if it spins on by hand all is good. Trouble is the pitch isn't stamped on my nuts & I soon mix them all up in my bolt box. I confuse myself with great ease - with my Dad not being around like the old days I have no one to ask except here. (Note to self use different boxes for different pitches with label on box)
This opens up a new can of worms for me as I'm a bit old at 74 to be an Apprentice but in many ways I still am.
Back in the 1960's I was using my AVO meter almost daily - these days I only use it for the V bit A&O don't live in my brain any more.
I found myself re-learning lost skills when working on my 400 but I've been to bed a few times since then.
I realise now on the 500 not only is it a bit different but the learning curve has turned back into more of a dip!

Stick with it Ted. There's always a few dips in the road on any journey. 👍😁

I learn every day just reading the forum. Poor day when we stop learning Ted!🫢

After looking at the thread damage on my fork lock nuts and one of the top threads on the long rod I have decided to not fit any pre-load spacers to the front forks - leaving it as standard as both spring legs are well within limits.
I've ordered a pair of new lock nuts from DS as there were a few other odds & ends I wanted from them - I will run a tap down the flattened thread to clean it up plus a die down one of the chromed fork top nuts on the same side.
I will fit the fork springs with the closer wound end at the bottom as this seems to be the consensus.
I also need to fit a couple of Helicoils in the right fork leg as the threads for the front fender fitting are not in great shape.
