I own an ’04 Z1 FR (coil). I was switching out the spring weights and oil, and had a question.
The damper cartridge for the rebound slides effortlessly through its motion when I pump the cartridge to remove the residual oil. No issues there. My concern is with the ETC cartridge.
When I try to cycle the ETC cartridge, it is difficult to get the cartridge to move without some effort. It is almost as if it catches on something or hits a snag in the travel. Is this normal? It is nowhere as smooth a movement as the rebound cylinder. I thought at one time I was told this was normal, but I can not remember.
