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.

I actually tried this about 3 hours ago. It doesn't work. The studs fit through the holes (with a little work), but the hole in the 49cc isn't big enough for the 66cc head's little sleeve fins to slip into. It sucks, I know...

I don't know if the hole in the bottom end could be dremmeled out to fit, but it looks like it could. I'm not about to try it though and risk ruining a second bottom end this week.
