Air Pressure in Front Forks ?

Postby silverider » Mon Sep 01, 2014 9:36 am



What air pressure should I carry in the front forks on my 1999 GL1500. I have a Hannigan side car.

If you have Progressive Suspension springs installed - No Air Needed.

If stock, follow Owners manual:

I believe the spec is 0 - 7 pounds.

Can you use the on board compressor to charge the front forks?

I suppose you can with the use of an extension hose, but due to the small amount of pressure 0-6 PSI, I would use a small hand pump as recommended by the service manual.

Everything I have seen about the front forks says use a Syringe Pump, and go slowly as the seals are delicate and easy to blow out.

Did some checking and decided the compressor is not the way to do it. Also the outlet pressure does not read on the display so you would be flirting with disaster.

Raise the front end off the ground.
This will allow the forks to extend .
Use a pointed object like a pen and open the Schrader valve so it sucks in air and equalizes the pressure inside the forks with the outside air.
Let off the valve - you have now allowed in maximum air volume which will pressurize when returning the weight to the forks.

Worth a try.. ;)

Interesting way to "fill" the forks. . . . Does this really work or ? ? ? ?

It works for ME - But I have Progressive Springs installed so there is no additional air pressure required.
However it DOES create maximum volume of air I think...
Worth a try...Using a compressor driven inflator can over pressurize the forks and blow seals so one must be careful..

I had never thought of that. Sounds logical.

Don't use the on-board compressor as it may blow the fork seals. I purchased a small hand pump at my local bicycle store that reads 0 - 10 psi. I use it to fill my forks on our '96 SE to 7 PSI.

This sounds familiar... ;)

Lifting the front doesn't raise the pressure much. The system was designed to have a specific "air space", this is why the oil level should be at a specific level. I have been experimenting with the air pressure and hoped I could learn from others experiences.

I have Progressive springs in the front and Progressive 450 IAS shock on the rear..
I haven't worried about air pressures in a long time
