Hello. I'm new to the forum but have browsed it and found a ton of valuable information here. I have a 2001 GL1800 RS trike with the adjustable preload. When i press the button to add preload it makes no discernable difference until I get to 19 only then can I hear the pump labor, this seems off to me and from what I read I think I need to add fluid. Has anyone done this with the trike body in place or do I have to remove it? Also I tried to email Roadsmith on where I would find information on my trike kit like build date but did not get a reply. Is there any way to find this information? Is there a number or date stamped into the frame somewhere? I was looking for that information so that I could purchase maintenance items like brake pads, rotors, shocke, etc. Thanks in advance for the help. Joe.
