Hi i'm Kenny and I am the owner of a 2003 Predator that i bought new in november of 03.....I have just in the past month had the urge to upgrade some things.....I have bought a 12-1 piston kit,vortex cdi box,pure polaris slip on, air box kit, jet kit and a 15 tooth front sprocket...Just looking for some good or bad comments as to the performance i may and or may not see with the work i'm doing.....Also i would like some ideas for the next mods.
