i like it
really woke up both of my sleds, first put it on my 00 sxr 600, noticed a big improvement there, had a buddy that would give me a hell of a run on his zr 500, put the clutch on, and i consistently pulled 2-3 sleds on him... i would say it is like going from a 2barrel carb, to a 4 barrel, also have one on my viper, and same results, woke her up a little... plus backshift is awesome either on a rolling punch or coasiting down hill.. love it
