Jim, do you mean to propose that ONLY springs, valves and oil can be changed in the fork tubes, or that valve emulators can be added? You listed the damping rod in the same sentence as everything else you wish to remain unaltered. The first job in installing emulators is to alter the damping rod with a drill to render it useless or it is pointless to take the forks apart.Originally Posted by UglyDogRacing
