This is for an F6B. The full wing is different, of course.

My bike would take about 8 or 9 clicks before feeling any resistance when adjusting the rear shock. It never mattered because I am a light weight. But, I finally got to fixing that.

The hardest part was figuring out which nut to turn. There is a 12mm threaded "nut" (hollow bolt) that goes into the adjuster. But first, you will want to loosen the 14mm locking nut. So hold the 12mm while loosening the 14mm counter-clockwise. Once it is loose, remove the 2 bolts holding the assemble to the frame. Now you can just spin the adjuster off of the 12mm "nut" (hollow bolt). Try to quickly hold both the hose and the adjuster "UP" to not lose much fluid. The 14mm locknut will have a washer and o-ring for sealing. Don't lose them.

First, you will want to have completely unscrewed the adjuster to its lowest setting. Once you have the assembly off, it will appear to be full of fluid. I had to do this twice because of that. Take something like a thin screwdriver and put it into the hole and gently push the internals down. Now you will have room to add fluid.

When reassembling, spin the adjuster on to the 12mm "nut", but not tight. Get it close and then remount the adjuster to the frame. Now you can tighten the 14mm with its washer and o-ring to seal everything.

Disclaimer: I am just a hack. Do this at your own risk, and good luck!

I just topped off mine, thank you for the write up. One thing you didn’t mention was the type of fluid it takes and I could find nothing in the service manual on it. I used DOT4 brake fluid.

I don't really know what to use. I used some hydraulic oil. The writes ups that I saw on the full wing, didn't seem to be particular about what was used. I think that we are both fine.
Thanks for the feedback on topping off the adjuster. Glad it worked!
