97 GL1500SE won't increase shock pressure

Postby Billv » Tue Jun 28, 2011 4:05 pm



I have a recent issue on my 97 SE related to rear shock air pressure change where when I push the increase button, the compressor kicks in as typical but the shock pressure does not increase. Decrease works fine, P Check also works. Any ideas of where I begin my investigation?

I'm going to bump this one as I'm having the same trouble on my '98. Anyone have an answer?

I had the same trouble with mine and was preparing to tear into the system. On a whim I hauled out the tire filling hose and lo and behold when i was trying to fill up the shock it was coming out the hose. Holding my finger over the end allowed me to fill up the system. It's not the most elegant of solutions but it beats tearing the plastic off....Mike

Your right MrMikey. I have a 99 1500se and when I bought the 10 foot air hose I thought I'd just leave it connected to the air outlet until I found that the air pressure in the shock was bleeding out through the air hose. Disconnect the hose and check for leakage in the valve, that may solve the problem.

The schrader valve in that air outlet hose is designed to keep the pressure in to pressurize the suspension. When you attach an extension hose to use to fill up something else, it opens the valve. When you leave the hose attached, then try to fill the rear suspension, it just blows the air out through that open valve, and instead depressurizes the suspension.

I have an '88 that will not pressurize at all so I am hoping it is just a faulty vavle also. I DREAD :roll: digging in to the system and removing plastics. Wish me luck... hahahaha

I always said that as well, but now that I have my 1500 torn apart, I have to say it's not nearly as bad as I thought it would be to remove all that plastic. Honda engineers did a pretty good job at designing things to be taken apart for maintenance.

I notice this thread is now 5 years old but...just now checking things for tomorrow's ride (S. Texas will be sunny and 70s!) noticed my rear psi was at 20. I started the air and after about ten minutes it moved 1 psi up. Immediately thought I need to go to Goldwingdocs...something is not working right. Sure enough found this old thread about disconnecting the extension hose...went immediately back out to the garage, disconnected that extension hose, and what do you know? - I was up to 35 in about ten seconds!
Thank you once again to everyone who takes time to share your experiences and knowledge! Who would have known, such an easy fix!
I will add a big plus for having that air extension hose. Got me to the shop after picking up a big ol' screw last summer, now I know to disconnect it when not in use :)
Thank you, Admin, for not deleting these threads just cause of age...the information is just as relevant.
Watching out for the "other" guy..be safe all!
