    RS Duke rebound problems

    just installed a RS Duke on my sons bike, went to adjust the air pressure for the compression and rebound but the rebound is not holding air pressure, any ideas what this could be.

    It's been a while since I worked on a Duke, but it sounds like you have the Pure Delite damper. As I recall the rebound had a standard dial at the bottom of the fork, and the compression had the air system to adjust the "threshold".

    So I'm not sure what you mean by the rebound not holding air

    on the bottom of the left fork leg is a air valve to adjust air pressure. when I hook up the pump it takes air in, but when you take the pump off the air comes out. guess its a bad valve.

    Left leg (non drive side) is the air spring. Positive spring on top and negative spring on the bottom. The valve is a standard Schrader valve, check the core to see if it is loose. If it's tight and still leaks just replace it with a new core.
