I have an 07 Dyna Wide Glide that I want to soup up. I've got it paid for now so I feel better about modifying it. I am a gearhead from the car days but don't know much about motorcycles. I am sure it's much the same, so the real power comes from the combination of parts.
So what's a good combo for a street driven Harley Davidson that runs no more than 93 octane?
