Portable air hose to use with built in compressor

Postby Cfg2nd » Tue Mar 19, 2013 6:42 pm



Hello all..... I hate to sound stupid...
My 1990 1500GL SE of course has the built in compressor for load and suspension adjustment.

I hope i'm not going blind but I cannot find where I can connect the air hose to use for filling tires!!!

Where the heck is the fitting that the hose screws onto? I have a brand new never used cloth braided hose that came with the bike.

It's inside the right saddle bag toward the front of the bag.

I also puzzled over that when I first got mine, and can confirm it is in the right saddlebag at the front, can easily be missed.
Are we having fun yet?

you need to purchase an extension hose to connect to the schrader valve in the right saddle bag.....

I was told on here I believe , that the on board pump is slow and can burn up if not used correctly on a tire...I carry a slime pump and use on board just for suspension...good luck

Make sure you do not leave the hose connected to the outlet in the saddlebag if you are not using it. Otherwise you will have no pressure in your rear suspension. Disconnecting that hose from the outlet seals the outlet, so that you can use the pump to re-pressurize the rear suspension.

So are you saying that when you use the hose that you loose the pressure in the suspension? After using and disconnecting you need th refill the suspension system?

No, the suspension will maintain its existing pressure. However, if you press the increase button with the hose connected, it WILL vent all of the pressure out of the suspension, and will not pump it back up - it will just send the air out the hose instead.

Here's how I understand that it works (sorry for my atrocious artistic skills):

GL1500 Compressor System
GL1500 Compressor System


There are two valves - a suspension valve and a relief valve. The compressor connects in between the two. The air pressure sensor also connects at the same point as the compressor.

When you press the "P.Check" button, it opens the suspension valve. This lets the pressure in the suspension reach the air pressure sensor so that you can read the pressure (and allows a tiny bit of air to escape in the process).

While holding down the "P.Check" button, if you press the "Increase" button, the compressor runs, pumping air into the suspension.

While holding down the "P.Check" button, if you press the "Decrease" button, the relief valve opens, allowing air to travel from the suspension, through the suspension valve, through the relief valve, and out of the system. This depressurizes the suspension.

Pressing the "Outlet" button will run the compressor with both valves closed, so air will be directed to the outlet in the right saddlebag. This outlet is normally sealed unless the air hose is connected, in which case it directs air out through the hose.

If the hose is connected and you press "P.Check" it will open the suspension valve and immediately depressurize the rear suspension through the hose. If you hold down "P.Check" and "Increase" with the hose connected, it will both depressurize the rear suspension and send all the air from the compressor out through the hose.

I hope this makes sense!

If you do not find the hose in the right saddle bag, it may be behind it. You have to pull it out of the bag when you take the bag off to do any maintenance behind the bag. The previous owner may have forgotten to put it back through the rubber grommet when the bag was put back on.
