in my opinion and experience unless your bike is running way rich or lean from mods i'd spend my money on something else, but if you do need one Owen at www.twowheeldrift.com gave me the best deal on mine, like $250 but that was kind of thrown in with my arata system, regular he probably does them for like $275
