Doesn't affect crank hp, or a brake dyno.
Does reduce the figure a Dynojet will report though (due to being an inertial dyno) though I wouldn't think by 3.5 hp.
Anyhow, is it different ratings by Kawasaki or by a magazine or whatever? You will see far more variance than that between SAME YEAR examples of the same bike in such tests, so if that's it, then there's no story at all.
