The basic design of the Sportster motor is still confusing to me, but my father and I will be working on it shortly. I'm sure once we get into it things will seem more resonable. For now I am left staring at the single cam per vavle configuration and just scratching my head.
The cams I decided to run were the Andrews N2 cam. The grind featured on these units is suggested for good mid-range power increase with an Xl1200 or an 883 with a big bore kit(my scenario).
