i am going to be rebuilding my old and tired warrior this winter and know that they just came out with a 11:1 piston for the warrior. does anybody have a 11:1 piston in their quad? my buddy has a 10:1 piston and it tops out at 68.7 on the GPS...(many other mods too....16 tooth sprocket..etc) anyways, how does it work and is it loads more power than normally?????
