My 76 Convert has the FAC dampers. While the ride is stable and comfy enough, I have bottomed the forks several times, and would like to add more damping. I run them with no air pressure, though they do seem to build pressure as I ride, because when I occasionally pull the caps and depress the valve it 'pishes' air.
I have no idea what the weight of the current fork oil is, and must confess I have not even checked the oil levels. I have icon rear shocks that work very well.
I've also not dealt with FAC damper inserts though I understand the concept. I rebuilt the air forks in my XS1100's and have swapped fork springs and changed oil on several bikes over the years, but all told forks and suspensions are the area of least experience. I've never been picky about suspensions, and have always enjoyed modifying MY inputs and approach to the bike, learn how it operates, and maximize it's capabilities/limitations.
Any recommendations on the best (cheapest) way to firm up the damping on the forks? I want to firm up the damping but NOT slow down the rebound too much to make the bike wallow. TIA
