How to fix / rebuild / modify a Husqvarna / KTM steering damper / stabilizer.

How to fix/rebuild a Husqvarna / KTM steering damper / stabilizer, plus a modification to add screw ports for filling and bleeding fluid. I did tons of research on these dampers and could not find out who makes it, and I could not find any other videos showing how to rebuild these particular dampers. Hope this helps you out. Thanks for watching.
