Im pretty sure the blocks for the 66cc and 49cc 2-stroke motors are the same right? Does anyone know if there is a difference in the cranks of these 2 sizes of motors? Would it be possible to pull the top end of the motor (head, cylinder, piston etc.) and replace with 66cc parts? Im not looking to do this anytime soon, just sounded like a fun project for sometime in the future. Thanks.
