I have a 2003 fatboy. Pretty stock. Just put V&H competition drag pipes on!!! Love them. I was wondering what you guys think is the BEST performance upgrade for my Fatboy...Carb...Heads..trans..whatever. Thanks for any advice.
Change the primary gear ratio to a 3.37 (from the stock 3.15) and here is why:

I 2nd that....gears first. Next plan your complete build and pick away at it if money is issue. Make sure all mods are compatable with each other. It is cheaper than buying parts twice ...like I have.[:@]
