Ok guys, I couldn't find the previous thread about the compressor controls can you help me out? I remember reading one thread about pulling the compressor controls out and cleaning it up to repair functionality. On my '85 1200a the rear suspension will pump up to pressure but after sitting for several hours, say over night, it's low again. I thought someone had mentioned on a previous thread about o-rings on the controls fixing a problem but I may be up in the night.

Suspension holds up well while it's got air and it's a slow leak, but when when Rodent rides with me she doesn't care for bottoming out on some of our "wonderful" pavement here.

Really hoping it's not a rear shock R&R.

When I bought my 83 Aspy it would pump up but leak out. I checked all the lines with soap and water but couldn't find a leak. I took the cover off the switches and carefully looked at them. The air "decrease" button was stuck in the pushed in position. I disassembled it and cleaned it up,put some light weight oil onthe O-ring and put it back together. Works fine now! :clapper: I try not to push the buttons any harder than necessary so they don't get jammed.

Thanks, Bob. Any tips on getting it apart? I've got a Clymer's but it's at home. Looks like I can work on it this afternoon though...

If I remember correctly, it's pretty straight forward and obvious once you remove the top cover. Small screws, parts and a spring under each buttonthough so be careful when disassembling. Once you remove the buttons, clean out the seats and buff them out with 0000 steel wool or something very fine if needed. I think I used a very light machine oil to lube the O-rings with.

Sinceyou are loosing air very slowly and only on the rear, I would just clean and lube the "REAR" check button first to see if that fixes it. Of course since you are that far into it, you might decide to do them all while there!

No special tools, equipment or knowledge required!

Thanks again. I didn't think there was a lot to it, but I couldn't remember the thread. I'm thinking that I should empty both front and rear systems to work on the switches?

Good idea! That will keep any loose small parts from being blown away when you break the seal.

The small screws on the sides of the plastic cover can be hard to get to and easy to drop and lose in the engine area. Use care!

Ues there was a thread about this recently. The air was leaking from the back suspension of a gl1200 into the front. The valve behind the control switch was to blame and some WD40 fixed it.
