I couldn't really tell much difference on mine with the OEM setup. As I've upgraded to Wilburs I can really tell the difference between each setting. If you can go back to the bike, with ignition on, but not with the engine running, cycle through the 3 options as you jump up and down on the seat. You should easily feel the difference in damping. If not then either the ESA motors are shot or the shock itself.
Thanks mate will give it ago. Work out how to change all he settings at the time. How much we're your wilburs for parts and how much for fitting. Going to try and beta free fitting deal in the price for when they need replacing
