I know this has been visited and revisited but here it goes...
There is a 03-04 GSXR1000 shock on ebay for $46 to my door. Here is what I am thinking, please let me know if I am incorrect:
1) An 05 measures 12 3/4" so this shock should be anywhere between that and 13"
2) I can purchase lowering links to keep the rear hight the same. (I'm planning on raising the forks in the trees to drop the front and quicken the steering, but at 5'6" want to keep it at the stock hight to lower)
3) This shock will have considerably more adjustment than stock and handle better.
Finally, how am I 100% sure the last owner didn't already change the rear shock? Any tell tale markings or spring color?
Thanks!!
