I need to know how to figure out the CC'S from a 67 bore and a 70 stroke. I used to know but forgot. I used the search function, but came up with nothing. thanks for any help.

 

cc's can be calculated by the following formula:

cc's=(3.14)*(R)*(R)*(H) (where R=radius, and H=height of cylinder: ie-stroke)

Using the dimensions you provided, the following would be true.

cc's=[3.14x 33.5 x 33.5 x 70]/1000
cc's=246.8

Regards,

Rog

 

Thanks rapidrog for the info.

 

here's another method that might be a little easier:
bore x bore x stroke x .0007854
Ex: 67.x 67. 70.x .0007854= 246.79cc's
