Big Bore
The big bore kit 865 along with the Race Two Into one, Ported head free flowing air box mods put out 71 horsepower the the rear wheel after tuning! Much more midrange pull. This bike is really a jewl waiting to be massaged the six speed transmission is one of the best along with a very well thought out frame that handles the extra power. Thanks Royel Endfield and S&S cycle for teaming up to build a Screamer for the working guy!
