    They are very low PSI but a better option is put in Progressive springs and forget about air ever again. That $80 was the best money I spent on my 850G and turned it into a different bike.

    Life is a balancing act, enjoy every day, "later" will come sooner than you think. Denying yourself joy now betting you will have health and money to enjoy life later is a bad bet.

      It will depend on your weight, two up, ect and the "settings" of the rear shocks.
      you can find that info in the owners manual. if you don't have a copy, you can find a pdf of one on Basscliff's site.

        You can experiment to see what works. The pressure is really low, with a max something like 20 psi. But don't try going even that high. I don't think you could destroy yours seals (unless they're borderline), but you might force some oil past them. More air will raise the front end and quicken the steering a bit. It was pretty noticeable on my L.

        But Scott's right. I finally got some progressives into mine. Much better than fiddling with air, and noticeably less dive on a quick stop. It's like the best day on air, only it's every day.

          12-15 psi should be good. The best way to set it is to have an air comressor/tank combo and set the tank pressure at your desired pressure. Then you will exactly equalize the pressure in the forks by applying the nozzle, holding for a sec and removing quickly.

          I also recommend pulling up the boots and applying armor-all to the fork legs, seals and boots. It really reduces friction.

          You may want to change the fork oil too: it's pretty easy to do

              Hi Mr. pcdonny,

              Before I put Progressive springs in my forks, I would use 15 psi to get a stiffer ride. But new springs and oil are the way to go, as soon as you get a chance.

              Be very careful when putting air on your forks. It's best to use a hand pump. The air pumps at the gas station will over-pressurize the forks very quickly. Be VERY careful. I think the manual says 35 psi MAX.

              I'm pretty sure I gave you a mega-welcome. If not, I apologize and invite you to CLICK HERE.

              Thank you for your indulgence,

              BassCliff

                I haven't gotten my progressive springs installed yet, but you might want to use something like this to pressurize the front forks (Progressive sells it I believe): http://picasaweb.google.com/lh/photo...eat=directlink

                    I believe the recommendation for my GS1100ED was 7psi. Did a normal pump fitting work for you? My air tank attachments never seemed to work with it.

                    Also, DO NOT put Armor-All on your rubber stuff. It's petro based and will degrade the rubber. Armor-All is good for nothing that I can think of. Please correct me if I'm wrong, but that's what I've read.

                    There is a suspension-specific aerosol cleaner that should be available at motorcycle shops.

                    Be sure to get dead insects off your fork tubes. Their bodies are actually very sharp and damage your fork seals. If you have any surface pitting, get at it with either 0000 stainless steel or a diamond file so it doesn't get out of hand.

                      If you want to put anything on the seals/forks I would wipe them down with WD40

                        This is how I did it for years. A portable air tank also does the trick, with a good quality tire chuck on the end. Super-safe, easy & no worries about unequal pressures.
                        and God said, "Let there be air compressors!"
