So when I finally hit a faster track, I realised 2 things:
1.
...dbrace was right. the fork was diving at an alarming rate! In fact, the first track I tried was too slippery and too slow. I now realise that I was not using the front brake hard enough and the fork felt fine! On the faster track however, I had a better grip I was 4th gear WOT in some sections. Stiffening with compression clickers and increasing the external fork pre-load to 4 turns IN helped a bit but not much. Grabing the front brake at high speed in braking bumps resulted in a RAPID and DEEP front end dive, making the bike totally out of balance.
2. Under the following link,

Jeremy debates on independent vs non-independent valving. The way I understand it, the 0.2mm cross-over makes the LS and HS valving VERY independent (please tell me if I am wrong here).
What I felt on the bike was a lack of consistancy in the damping. It felt plush and smooth on some bumps at a certain speed. But it felt much stiffer and even harsh at a higher speed in the same section (I almost lost the bar when entering too fast in breaking bumps!)
Unfortunately, I didn't have the shims to try a non-independent valving stack. So instead, my 2nd valving mod went like this:
BV stack (2nd trial)
(3x)24.1
14.1 (instead of 2x14.1mm)
22.1
20.1
18.1
16.1
14.1
11.25
MV compression stack (2nd trial)
lift=0.3mm (unchanged, 0.5mm was a measurement error)
(3x)24.1
14.1 (instead of 2x14.1mm)
22.1
20.1
18.1
16.1
14.1
10.5 (spacer)
MV rebound stack (2nd trial)
(4x)D.1 Delta shims
20.1
18.1
16.1
14.1
14.1 (back to where it was)
10.3
16.25
... and it felt a bit better. Diving was much reduced. Although I still believe that stiffer springs are necessary. Bottoming resistance is great too. But I lost high speed plushness. The bar has now a tendency to 'vibrate' in braking and accelerating bumps... the ride is a bit more tiring.
Well, I believe this setup is better than stock, but it can certainly be better. Next, I'd like to try stiffer springs and a non-independent valving set-up...if I can get shims...
It's just fun to play with those things...
Kind regards to all,
