So, tell me if I am wrong, but the stroke of the crank along with the size of the piston both effect how many cc's your bike actually is right?
If so, does anyone know how to calculate it?
Also, with all the talk of using different cylinders on puchs and such, are there any effective scooter kits or any other kits that are super effective and NOT water cooled. That water cooled stuff is silly.
