Bike is as in signature...I am looking for a mild upgrade cam set. Also, cam drive recommendations... I do not want to upgrade valve springs. I am not going to upgrade the jugs etc. I am going to stop at performance cams... I truly love this bike and it's performance but, I cannot leave well enough alone and upgrading cams seems like a good play from where I am... S/F Bill 2008 FLSTC.
