using a +3 crank
72.00= 244CC
72.25 - .010 = 246CC
72.50 - .020 = 248CC
Here's a list of all bore sizes converted to cc's
Bore....over.....stock stroke....+3mm
66.00 - stock = 195CC - 205CC
66.25 - .010 = 196CC - 207CC
66.50 - .020 = 198CC- 208CC
66.75 - .030 = 199CC - 210CC
67.00 - .040 = 201CC - 212CC
67.25 - .050 = 202CC - 213CC
67.50 - .060 = 204CC- 215CC
67.75 - .070 = 205CC - 216CC
68.00 - .080 = 207CC - 218CC
68.25 - .090 = 209CC - 220CC
\/ big bore cylinder/sleeve \/
72.00 -........=232CC - 244CC
72.25 - .010 = 234CC- 246CC
72.50 - .020 = 235CC - 248CC
hopes this helps
Sorry, respectfully say I think your response is flawed. Can you share the details of your calculations?
I was questioning the math related to cc's added with stroke.. not the math on the cc's added with bore.
240 stock stroke on a big bore. You show 244 cc on a stroker with stock bore. In my math, I show that with the first mm of stroke. Then I took into account 3mm of stroke. Pie x radius - squared x mm of stroke.Respectfully you are wrong. You asked for help, I gave you the correct answers. If you don't know how to calculate it then how did you come up with my answers being wrong? I could put it on paper for you or type it out but after being told I am wrong I will keep you in suspense till you figure it out. Good luck
