I've heard tales to barely noticable (I take that as no change), to it cured their grandmothers broken hip.

Another YFZ450 owner that wears pink O'neal riding gear to beat you at Comp Hill.

That was the secret mod when I was looking at hot rodding my 400. Suppposed to give you better squirt out of the corners or more torque, not much more if any horsepower. Like you, I heard little if any improvement or it's the greatest thing since sliced bred. Haven't tried it though.
