It does? It shouldn't increase at all, or at most marginally, because of the tabbed washer. I'll try again with someone holding the forks up while I set the preload. Really don't want to disassemble everything just to take the forks out.You can get the preload set nearly perfect, but when you tighten the nut on top of the triple clamp, the preload will increase. Bear that in mind when adjusting preload.
IIRC, there should be very little resistance to moving the assembly (without the front wheel on). You want to adjust for very easy movement, but with no slop.
You'll get it.
