Has anyone found a decent way of adding pre-load to the USD KDX forks? Spacer between the spring and cap or something?

Which model forks are you referring to? The KDX200 has too much, and the KDX250 is just about right. I would say no more is needed. Stiffer springs may be needed, but not more preload.

No. They won't work. The outer diameter is too large. Sorry.

Springs from FRP or Race Tech were the only ones I found to work. I suggest going with the Race Tech springs.
