GL1200 Air Supension

[mickyc]

Hi all,
My 1984 Aspincade has an air suspension mystery. I can hear the compressor working, I cam see that it starting to pump air into the suspensions, but after 2 sec all air comes out.
That is the situation from day one when I got the motorcycle abut a year ago. It didn’t mine me but after replacing the rear tire, when I'm with another person on the bike, the rear tire is rubbing with the mudguard.
Any suggestion where to start looking resolving the issue?

Thanks,
Micky
