Rear Air Shocks

Postby rjbrownley » Sat Feb 26, 2011 4:01 pm



I just had to remove the rear wheel on my 83 interstate. The instructions told me to remove the air from my shocks. When I tried to remove the air by using the fill fitting on the side of my bike. Instead of air coming out, all I got out was oil. This does not seam right to me. Anyone know what is going on?

It sounds like sometime in the past one or both of the shocks were inverted, or layed on the side. I'd go ahead and let the air/oil out and measure just how much there is. If it's a miniscule amount no worries. Since your going through the drill of removing the rear tire you can continue and take the air lines loose from the shocks and blow any oil out of them. Then button everything back up.
If the shocks have never been serviced then you can go ahead and disassemble them give everything a good cleaning, new oil and that would be one less thing to do down the line.

Thanks for the info. I will clean out the air line today. I have also been planning on replacing the shocks.

it is a lot cheaper to rebuild your rear shocks than it is to replace them. Progressive Suspension springs ,new seals and fresh oil should cost under $100. Thats what I did to mine ,I couldnt believe the difference in handling.Best money spent on the bike so far.

Thats a good idea, I did not know that you could rebuild them. Does Progressive have a rebuild kit? Thanks

They dont have a kit that I know of but you can buy the replacement springs from them ,get your seals and oil from another source of your choice. you can even buy replacement dampeners if you feel the need. Once you have the shocks off the bike it should take you about an hour to strip,clean and install your new components.

here is a link for the springs at a good price. better act quick cuz there is only 2 left at this price.
