I can confirm this ... I have a 100mm extension on The Dobber (see linky in my sig) and you can still feel the jack but only in high torque situations (like me hitting the throttle because it's a frickin' hoot).
But I will also say that on the highway, you can give it gas and the bike rises a bit. Because of the lengthened arm, I'll bet the effect has been reduced by at least 50%.
