Update: Worlds Fastest Briggs and Stratton Custom Motorcycle! Seriously.

Updated with more pics!  Thanks again Bob!  And once again Nice Job!  I REALLY like these sorts of builds.  Very Creative.

Bob Decker sent in some pics and links to this really cool custom Briggs and Stratton powered custom but this is the only one I could get to that was big enought to use. I’ll update the post if Bob can get me some more. I love this concept. I’ve looked at the big Briggs engines and before and thought that they were plenty powerful enough for a motorcycle. 35 HP and 52 ft lb of torque ain’t bad!  Guess I was right! Thanks Bob!
