thank you for the polite welcome . I purchased a 1988 royale about 2 1/2 months ago and I love it besides the weight . Yesterday I was riding and by the grace of God I was able to get it stopped after a 80mph tear blowout . After getting stopped and looking at the tire . That I know was good few days prior looks as if my rear suspension had gave out and wore it down to trash . I do know that I’ve never heard the air compressor work but the computer on it does come on just can’t adjust it up , down etc . So I’ve got to purchase new rubber n trying to get a head start on troubleshooting the air suspension and help would be greatly appreciated
