And thanks again Fossil92!!!! You are so damn helpful!!!! If you need any advice on military trainer jets , please ask!!!!!Actually the air compressor is only for the rear. There is one air shock on the rear of the bike, the other is regular. The forks only get air if you manually put it in.
Remove small plastic screw on caps at top of forks. You will see schrader valves. Now here's the Important Part. DO NOT use a regular tire inflator unless you have a regulator that you can turn way way way down. The Front forks take very little pressure 0-6 lbs I believe.
They make a small hand pump to put air in. Or you can do what I used to do & use a bicycle tire pump.
When I put the Progressive springs in my '95 I stopped running air in the front fork. What a difference they/that made. If you want to do something relatively cheap for yourself that's a good one to do.
