I have an 08 FatBob. Taking it to a Stage one with Screaming Eagle A/C and Kromewerks slipons. I'm looking in the Screaming Eagle Catalog and they have a Street Legal Ignition System. Would I want to change this at the same time I change to a Stage One? Why would you want a different ignition system? What benefit would my bike achieve? Is it worth it? Any comments would be appreciated.
