I have always wondered which fuel distribution system type was superior as far as performance goes. I know fuel injection is supposed to be more reliable, but how about performance? Can you do more enhancements to a carburetor therefore have an advantage over the fuel injected motor. I have owned both, but never been able to compare apples to apples. My '06 1200 Custom is supposed to be the last Sportster with a carburetor. I would like to compare an '06 to an '07. The '07 being fuel injected. Anybody know?
