Scott, Does your bike still have a warranty? The spring preload adjuster can be known to break and this sounds like what has happened to yours. The preload adjuster is available from Kawasaki (part no.
43094-0002 ) but then you still have the same risks of this part breaking too. You could replace the whole shock with a used unit but these are known for having a very soft spring. I sell several different springs that could make your stock shock stiffer or you could go with either the 420 or 465 series PS shocks, as these come with a very stiff spring. The PS shock spring would probably be too stiff your weight. If you wanted to go with a PS shock, I could swap out the stiff spring these come with for a softer spring that would still be much stiffer than the stock shock and spring. The PS 465 series shock is actually a pretty good shock. This shock has better damping control, better seals and a larger shaft to resist bending.

DSN_KLR650@yahoogroups.com [b]Subject:[/b] [DSN_KLR650] 2008 KLR650 - Wanted: used rear shock / replacement recommendations
My rear OEM shock is fixed in position 1 (out of 5); the spring preload adjuster bolt just spins freely.
Local dealer recommends I upgrade to Progressive [model 465 for the 2008 KLR]. I've read mixed opinions about the Progressive 420 vs. OEM model, but not as much info. about the 465.
I'm 6', 160#, and ride 85% street, often with loaded panniers. It seems heavier riders prefer the aftermarket springs? As a novice rider, would I really notice the difference?
I'm interested in any used rear shocks that would fit my bike. I lean towards finding a used OEM shock. Since this is my first bike, I'd like to ride stock until I learn more.
But I'd also appreciate any opinions on options for repair and/or replacing the shock with an aftermarket version - as well as your experience with aftermarket shocks for post-2007 bikes.
