Thanks for the advice but I've tried all that. I have the 2 spanner wrenches and it will turn to increase load (downwards) but will not turn to decrease load (upwards). The Ohlins manuals are terrible and it's the same that they have on the website. There are no visuals. Or them telling you what the max/min are. I actually think I have hit the max - hence it not moving upwards anymore.

I think from the looks of it, it's maxed out. I can increase it, but not decrease it. I'm going to call Ohlins and ask them for a softer spring. This way I can always increase preload if I need to. Right now I'm stuck at the lowest setting it seems.

No I cant. Those rings Cannot move to the top just by turning the cams. They do, however move down, which increases pre-load. Also, if you look closely, it is not threaded. It seems you have to remove the shock to decompress it, then somehow.....move the two rings upward. It's weird really. All the pics and research I've been doing you see a "threaded" shaft. This shaft is not threaded. It's grooved rings. I count that there are 6 rings left so likely I'll be able to move them upward at least by 3 to 4 before maxing out.

So I called the people from Ohlins and now understand the mechanics of the shock. The uppermost ring is held in place by a circlip. The only way to move the cams upward is to remove this circlip, lock it onto one of the rings/grooves above it, then slip the cams back on. This of course can only be done when the entire shock is removed, spring is compressed, taken out. Then the cams, which are one piece really, slip right out.
Interesting note: depending on the spring rate, each ring on the shock represents 4mm of movement (up/down). Assuming my ideal sag is 25mm, then the cam(s) will likely have to be moved up 8mm (two ring notches), so if need be I can adjust downwards and increase preload to compensate. The cam units allow for only two turns in the opposite direction.

In my experience the ramped adjusters are only good for changing preload to add a passenger. To set sag preload you must change where the circlip is on the body. It's a pain I know as the spring must be removed to do this.
