for Dyna owners running HD air shocks
was wondering what your ride was like?
i just installed 12" street glide shocks on my 11 wide glide,
currently running 25 lbs of air in them and mine sort of floats
up and down on bumps, i dont remember this type of floating
ride action on my nightster when i installed the air shocks on it.
im wondering if the shocks need to have the oil replaced
with a 20wt or if they may be low........

My guess is there isn't enough weight for them. I run 25 psi on my Road King when riding solo, and 50 when two-up. And that's an 800 lb bike.
I'm not sure you can safely (for the shocks that is) go lower than 20-25 lbs of air.

Is it doing anything bad handling wise? Does it bottom or noticeably bounce up and down? I've run mine as little as 0psi to as much as 35psi 2-up. Go for a ride and put your feet on the passenger pegs, gives a good idea what is going on back there. I have currently have about 25psi solo and it rides pretty nice I think. You can't really compare the pressures on a Dyna to what a touring bike uses - the touring bikes have the shocks nearly vertical, not to mention they weigh a lot more whereas the Dyna shocks are at a great angle with greater leverage and they are lighter.

its more a rebound issue in the corners, straight lines it just glides over the bumps
and wont bottom out unless an extremely heavy bump... but if i hit any kind of
heavy bump going through a corner it bottoms and then on rebound upsets
the handling somewhat. very disconcerting to be honest this is why i was thinking
of a heavier weight oil.....

Sounds more like one or both may be low on oil rather than too light (there is no specification on what is in there) - ZDid you get them new and if not do you know that they were capped on removal? Mine give a very smooth controlled ride under pretty much any conditions.

Did the air shocks have the plugs in them when you got them? Sounds like you have no shock absorber action, just air springs. That would be the case if they were extremely low or out of oil.

I run 30 lbs in mine solo (I weight 175 lbs) on the Fat Bob. I felt like less air let them bottom a little too easy -- or maybe I just have crappy roads on my commute.
Don't have a problem with a "floating" up and down sensation. Mine were new Profile Low Touring (54635-09).
The ride is definitely different than the springs and I'm not sure it's better -- smoother yes, but not sure better.

they were capped but had seepage in the box they came in
also no telling how long they were seeping after the PO took them off
and stored them.
what is the best way to remove whats in there so i can start
refilling from scratch?

Great thread. I have been toying with the idea of running air shocks as well. Can anyone tell me what air shocks I could use from a tourer that would fit my 2000 Super Glide?
Also I do mostly solo riding and when cruising I like the slammed/lowered look (currently have Burly's), would I still get that look or would it bring me back up to where the original 13" shocks were at?
