I have an 06 V2 and am finally going to order my dyno jet kit for it (have a 2" hidden snorkle on it with a reducer till I get the kit). But my question is, the kit for the cat 650 is $74.95 through royal distributing, but the kit for the brute 650 is $69.95?? Why the difference is it not the same engine?? Also I read somewhere that the KVX 700 kit might be the better way to go because of the bigger jets? Is this true, I am at 2-3000 ft. Thanks for any help.
