losing air pressure on right rear shock

Post by UncleStu62 »



Hello all, my 92 GL1500 Interstate is gradually losing pressure in the right rear shock. I pumped it up to 25 psi, but by the next day after a short ride, it was down to 16.2 psi. I did notice that there appeared to be a little bit of oil on the end of the air hose (valve end), but after wiping it dry, and riding it for a while, no further oil was noticed. Any tips on where to start? I sprayed some soapy water on the valve end of the air hose, and the banjo bolt at the shock, but did not notice any bubbling. I sure would appreciate any tips on what to do next. Thanks!

Just follow the lines with your soap spray. There are some solenoids and a manifold block you need to check, too. If everything else is air tight, it's probably the shock.
You are aware that you are only supposed to check and adjust your air with the bike on the center stand?

Thank Rambozo, I appreciate the response. My bike only has the manual air line, no onboard compressor, so it's a really simple set up. I can't find any leaks on the line itself, so I figure it must be the shock. I'm hoping there is a way to rebuild the shock, or perhaps I need to replace it as a unit. Maybe someone will chime in. And yes, I have the bike on the centre stand for this project.
Thanks again!

I missed the Interstate part. Not many of those around. There are still rebuild parts for the air shock, but I would act fast as you never know how long before they get discontinued. The boot is always destroyed, but there is a Monroe or NAPA replacement that works great for less $.
