'82 Aspencade air shocks bottom out.

The rear air suspension on my '82 Aspencade has been bottoming out with my light weight wife on the back. The system has a slow leak evidenced by the need to refill the shocks a couple times a week and daily on longer rides. How do I fix this issue?

Rebuild the shocks. I'd check the air valve, hose connections etc. for leaks first but if you don't find the leak =rebuild.

If the shocks are original, the springs may just be tired and worn out. My GL1100 (with original shocks) was like this. I replaced them with a set of Progressive 416's, and the bike sat up a good inch and a half taller at the back as it was restored to the correct (original) suspension height. This also obviously fixed my air leak and oil seal problems.

Admin. When you say you replaced the springs with Progressive 416's, did you replace the inner springs in the original shocks or did you replace the whole shock? Where did you purchase them (which ever you purchased, shocks or springs)?

I replaced the whole shock - springs and all. They came from Cyclemax

Just looked at the cost of new Progressive 416 shocks and I think a rebuild is worth a try. Is there a thread that explains that process or is it as simple as removing the shock, taking it apart, and replacing a couple things. Like springs? There is no indication visible on my shocks of who manufactured them. Just big letters "AIR SUSPENSION".

I had very much the same problem, also on an 82 Aspencade. Too-soft suspension even at max pressure, and the bike sat very close to vertical on the side stand. I replaced the front and rear springs and seals with Progressives, but I kept the actual shocks. Made a big difference. Much better handling, sits higher, rides great. I highly recommend this. Wasn't too hard to do.

Profneilwalker - how did you do the shock rebuild?
