What inch is your bike? Quit the good torque number there. Tell more about your build if you will.

I don't plan on going into the heads, so I think the 570 is on the very short list when I finally pull the trigger. I plan on keeping the stock mufflers (God I'm getting old), new FM 2-1-2 headpipe, already have the Power Vision, decatted pipe for now.
Thanks to everyone that posts up their results here. It is so great to see the options come together with real world info.

HAHAHA You're a funny guy Hoss. A drag pipe lover gone soft so the radio hater in you can listen to your stereo.

Dammit, everything you say is true!
Thank goodness I still have the old King with the Thunderheader and no radio.

Fillyfan That is what I am looking for. It would be nice to see the HP go up a little more and a little sooner. Still a nice pull for a touring bike. Did you do any head work?
