Rear air Shocks

Postby jhill9365 » Mon Jan 25, 2016 11:26 am



New to the forum. I just got a 1982 Aspencade and I am losing air for the rear shocks. I have checked all the fitting and can't find any leaks. Could I be losing air from the shock itself?

Definitely possible. If the seal on the shock is failing, it can lose air.

Take a solution of soapy water (little bit of hand soap, a bunch of water) and put it in a spray bottle. Pump up the suspension, and spray around all the fittings, and on the shock, particularly where the shaft goes through the seal into the shock body. If you see soapy bubbles, you have just found your air leak.

Don't forget to test the suspension adjustment valves as well - they are just schraeder valves, and the rubber inside them hardens out and causes leaks after a number of years. This is a very simple and cheap repair - you just replace the inside of the valve, you can buy them at any auto store for around a dollar.

Where are the suspension adjustments valves? I can't put two up it drags. Slow leak haven't done the soapy water test yet. Still sleeping for the winter will be up soon the temp is rising. I would much rather spend few bucks on valves rather than all new shocks. :idea:

here is a link to what I did to my shocks. Parts lists is on the last step.
I think it is cheaper than a new shock.

I took those air shocks off the bike and replaced with coil over. Great improvement. Are you rear shocks worn? Lift the bike off the kickstand and rock the rear up and down. If those shocks are worn get rid of them. NEVER ride with worn forks. You could kill yourself. I had mine redone with new springs and bushings. bushings alone do nothing if springs are worn. Lift the bike off the kickstand and rock the front.

I'm pretty sure rear shocks are worn out. Tight turns it will scrape pavement. Under heavy load it bumps.
I like the idea of prog 416 just don't have enough green.

With the bike on the kickstand, grab the rear bike rack or sissybar and push downward hard. you will be able to tell if anything is there. It should act like a good shock.

Check out ebay for the coil over shocks. I got another brand than progressive last year and the are fine in my opinion. I believe made in china. I think they were about 160.00
