Two engines are NOT better than one.

 
 

 

 

 

  My first choice of engines was an old Rotax 339cc two cylinder that came out of a snowmobile. I liked the thought of using this on such a light machine just because everyone said I was going to kill myself on it. Before I got the opportunity to do so, I melted one of the ignition coils due to a loose spark plug wire. This happened on the very first test run. Then in a fit of rage I tore the whole bike apart and instead of trying to get a new coil I decided to get a new engine.  
   
   
  My second choice was a vintage Briggs & Stratton. Weighing in at 135 pounds this beast puts out 16 horsepower and a max rpm of 3600. Due to it's enormous height the base of the engine had to be dropped three inches to allow room in the frame. This required a whole new frame to be constructed.
