I have a 2000 Fatboy carb'd and I had a friend give me a Screamin Eagle ignition system for it. I did a little research on it and it increases the rev limiter to 6,200 RPM and decreases the ignition timing 5* at full throttle. It definitely pulls stronger but I am just curious as to how the 5* timing change factors into it.
Inquiring minds want to know, lol
