I got a 04' XC SP 600 liberty 6200 mi. As far as I know all is stock other than V-Force 3 reeds I just installed. I also tightened my straps all the way down which increased my handling 100% on the trails. I am an aggressive rider that likes to be on the "Edge" and keep my heart rate up there. I am looking to mostly do clutch and carb mods.
