How to classify a Sportster engine with
Buell heads? We are going to consider it a Stage Two engine because they are standard
equipment on the Buell and a bolt on component for other Sportster based engines.
These results are impressive for a street 1200. If you are looking for a fast way to bolt
on power, the Buell heads are the way to go. If you look at the specifications closely,
you will see that with the carburetor was modified to the CV carburetor specifications
listed on this WEB site. The bike also uses nothing but Screamin Eagle slip ons for an
exhaust system. All things considered, this is an excellent example of a set of
conservative components installed and properly tuned giving above average results.Stage Two Engine Specifications
