suspension problem

Postby fynespirits » Tue Oct 13, 2015 7:06 am



I am having problems with my 82 aspencade air suspension !
when I pump up the rear shocks , some of the air finds its way into the front forks !
am I right in thinking that the 3 way valve may be at fault here ?
I am thinking that maybe the seals are worn or maybe the valves need a clean ?
don't want to make bigger problems than I already have if I am barking up the wrong tree !!
cheers all


The wrong side of 30 yrs old ,

How are you deciding that air gets into the front forks?

The correct way to adjust the shocks is to do the rear, then do the front. The reason for this is that leftover pressure from adjusting the rear shocks is in the system, so when you check the front, it will add that pressure to the front. The front then looks as though it has taken on pressure from the rear (which in effect, it has).

My suspension adjustment routine normally consisted of hitting the rear button, pressing increase to bring it up to where I wanted it, then pressing the front button and hitting decrease to bring it down to where I wanted it.

If I set the pressure the way you are saying , then the rear goes soft and bottoms out after about 30 mins of riding !
and the forks have aquired more pressure than they should have !!
this is why I think it may be the 3 way valve at fault ?
could this be right ?

Quite possible. Those valves are actually just standard schrader valves - so you can go to a local car parts store, buy a package of valve stem cores (about 50 cents each), unscrew the old ones and screw the new ones in place. Most of the time that solves this kind of problem.
