How to set preload on forks with different springs?

@PainfullySlo , if I recall you use different springs in your forks to get that "in-between" spring rate, but maybe others do as well so feel free to pitch in. So how do you set preload on the forks if you go with different spring rates in each fork tube? Do you set them equal by displacement (basically same number of turns) or do you set them equal by force, which would result in different displacement?

I recently changed my springs 1 size up in stiffness (from 10 to 10.5) and now they're a bit too stiff, so I'm thinking maybe I should just swap one of them back, so I'll end up with a combined rate of 10.25 N/mm.

Why does it matter? As long as you're not cranking one of them down too far, just keep them within a reasonable range and adjust them as necessary until you get the desired setting

Set them the same. Consider the 2013 zx6r forks. They only have one preload adjuster. It works. Don't worry about it. Not enough to make a big difference.

I know the 2013+ have preload adjuster on only one side and it always baffled me how it works ...but I suppose that's no different than putting 2 different springs on.
