1982 Aspencade suspension leak

Postby echinus1988 » Sat Jun 04, 2016 2:11 am



Well, I am so close to being able to ride this bike and what happens? A new problem.

My front forks hold air now but the back shocks are leaking all of a sudden. They have leaked a little air, now they leak out in about 5-7 minutes. If I push the front to check air, the rear leaks out immediately.

I changed my Schrader valves in both. Tightened them down really snug. That's how I got the forks to stop leaking. shocks still leak.I can't figure out how checking the front causes the rear shocks to leak out all the air. I'm beginning to wonder if my Schrader valve is somehow being held open.

I haven't been able to replace the o ring on the selector valves yet but I am trying to find a replacement for that.

Not a lot of information but any suggestions?

Thanks

Ok, I finally found a leak.

It is the little tower near the middle. I am pointing at it in one picture. I pressurize the system and it is bleeding air like crazy out of the little hole near the base. Bubbles coming out of the little hole.

Can I take it apart? Does it need rebuilding? What is it?

Ok, took care of that leak above.

I am hoping someone will have a suggestion for me.

I moved up to the valves that control the forks and the rear shocks. The reasons are that I cannot find any leaks anywhere else in the system for one. Also when I check air pressure on the front forks, the rear shocks drop immediately to the front forks pressure. The front forks appear to holding pressure.

Today when I removed the screws holding down the plate holding down the valves I had a sudden pressure release from the front valve. It popped up. It was the front probably because I removed the two top screws and only one bottom. But still, if I understand what's happening it should not have popped either one.

Just guessing from the release of air when I removed the schrader valves, the front appeared to have more air than the rear.

Any ideas on what's happening? What is the possible cause?

I have replaced the schrader valves in both but don't have the seals yet yo replace.

I hope I can get some responses with ideas.

Thanks guys.

I either picked a very unpopular subject or everyone is out riding! I'll take the everyone is out riding.

Still trying to figure out the suspension and still having a major misfire when I accelerate at higher RPMs.

And of course a trip in two weeks! Well just have to do my best.

Ride safe.

You should always check and adjust the rear shocks first, then when you've done that, check/adjust the front. The problem is residual air pressure left in the system that will leave either the front or the rear (can't remember which) adjusted incorrectly if you do the front first then the rear.

In either case, if you re-check the rear after checking the front, you're likely going to have to do both again.

I just got in the habit of doing the rear, then the front, every time I did mine.

Ok. That's the way I do it.

Bought new deals but had to get smaller than I needed. It has slowed the leak by a lot but its still there so I'm picking up the correct size tomorrow and will see if that corrects the problem once and for all.

I also want to check the bike gauge against a digital gauge. Can it be manually checked using the rear button and the connection on the compressor?

That's bought new seals not deals.
