Got my 1000 mile service and finally had them dyno tune my SE super tuner pro. I don't understand this as well as some of you, I know more about the paint and looks of a bike. Lol. I have the SE stage 1 air cleaner, V&H power duals with V&H 4" blackout rounds slip ons. i noticed after the tune that the motor runs much smoother, there is zero popping and throttle is way more responsive. And it pulls consistently thru the rpms.
