Got the late 06/08ish gsxr shock installed but as it is rather stiff I bought an early 02/04 version w softer spring. Okay, it doesn't quite fit and swapping springs is iffy as that one is longer. So graft it on w a bunch of preload to make it fit or shorten it? I only rode a few hundred on it and it wasn't terrible and that was w 1/4-3/8" of preload it came with. My sv's zx10r (510#)shock is great but the spring rates match. The 300 is supposedly 320# stock(I know-for light weights) but I believe the gsxr is 524#. Things may be fine w all preload dialed out so just pondering what is feasible as in other model spring. Thank you.
