So today I get the backrest I ordered for my new to me 2005 Ultra Classic. I took the bags off to make mounting the backrest easier. After I removed the left bag I was alarmed to see the rubber on the rear air shock all twisted up. Now what???

That doesn't help me figure this out.

I don't think it's twisted. That's just a rubber bellows to keep dirt off the shaft. It looks like maybe the bike was washed with something that didn't agree with the rubber and it "puckered". Or maybe it overheated somehow?
The shock itself can't really "twist". It's anchored top and bottom.
Pic of mine (non-belt side) for comparison.

Thanks BC , I answered you but I f'ed up the edit so I erased the whole answer I wrote. To me it looked like the bellows had been sucked into the shock from the air system.I don't know if that can happen as I am not familiar with this bike/system. It rides ok with just me but it rides extremely hard with the ol woman on the back. Yeah's she's a fatass but my VTX rode a lot better with her on the back and I used the "comfort" of the Ultra to sell the buying of it.It registers at 30 with me and close to 90 when she's on it.

I had air shocks on my softail Deuce (progressive air ride) and on my electra glide. I may be a minority, but not a fan of air shocks. That's why I posted about the progressive 412 HD. They were $220 and the ride is a BIG improvement over the stock air shocks. I ride two up most of the time and no more bottoming out. Plus, I got the 12 1/2 inch which lowered the back end 1". makes it a lot easier to back the bike up (more leverage).

Oak, I might have to look into those. I'm not a big guy and backing is a bitch for me. I need more leverage. And I'm totally lost on gravel.

DaBear, what do you mean 30 and 90? PSI of air pressure? The shocks on my bike use as little as 5 PSI for a light rider, up to 50 PSI for a 300 lb rider.
As for being sucked in, I'm not sure that happens. It might. They're pneumatic not hydraulic so it's possible. But the bellows isn't meant to hold air pressure, so if it was in direct involvement with the air chamber, that would indicate a seal leak. I think.
Do they both look like that or just one side?

Thanks Oak, will look into those if I can't fix this.
No BC only the left one is like that(see pic) Yeah that was for pressure. It runs about 30 for me and I weigh 300 and the woman is on when the pressure is close to 90.

hey Oak,what all is involved if you remove the air shocks for non-air...do you have to remove the electrics,etc for it or can you simply just disconnect the tubes and rock on? I'm 6' 2" so do I stay with stock length or go up a little?

10 minute job. put bike on a lift and raise it so the rear tire is just touching. Unbolt and replace one side at a time. Just disconnect the air lines and leave them if you want.

With the 412 HD I went with 2 clicks of pre load as total weight with 2 up is around 300 lbs. You can play with the preload based on the maximum weight on your bike. At your height I would stay with stock length.

The first thing I did was have my seat reworked by Bitchn Stitchn. They recontoured the seat so my legs fit closer to the bike, decreased the height and installed gel pads for rider and passenger. The seat is awesome. Now with the new shocks it is just about the way I want it. (IMG:style_emoticons/default/banana.gif)

I've decided I am going to shitcan the shock shocks and go with some heavy duty shocks. I tell you, I've about had it with BS problems with this thing.

I would go with the 412 Heavy Duty. If too stiff you can decrease preload. If you were up to 200 lbs and did little 2 up then the standard springs would be better.

Now I just need to address my front suspension.
