Hello everyone, I have an 85' FXRT that is starting to cup front tires. The air suspension does not hold air. When I fill up the fork and accumulator, she rides great for about 10 miles. Then the pressure goes to 0. What is the best repair for this setup? Should I ditch the air suspension setup? Can you convert the front forks to conventional? The bike is mint and stock. I want to make it look original. Any suggestions?
