I bought my 2006 Super Glide years ago and never really did any performance upgrades other than the stage 1 air cleaner. Everything else on the engine is stock. I would like to play around with it and try to get a little extra hp from it. What would be my next step? New cams? Can I do new cams only or do you have to do a lot more engine work at the same time?

 

Cams (and cam chest innards), displacement upgrade, port and polish heads, bigger throttle body.... in that order
