I want to take apart the forks to clean the insides completely and replace the oil and oil seals. I have changed the oil before, but have heard that just turning them upside down to drain does not get all the dirt/gunk out. My question is, do I need to remove the damper rod to do this service? I ask this because the dealer cannot find or get the damper rod removal tool, even though the manual has a part #. Is there another regular tool that can be used, or can I make something that will work, or should I just not remove it unless it is damaged which I don't think it is? Also, does a piece of PVC work as a oil seal driver, or do I need to spend $60 on one of those? Any help is appreciated.
