Hi all,

I'm just finishing a project and wondered what cc it is, i can't remember the formula.

my bore is 83.75 and stroke is 78.40

could someone jog my memory please.

Best regards

Si

volume of a cylinder = pi x radius x radius x stroke. If you want the answer in ccs, use centimetres as your units of length

If your measurements are in mm and your first number is diameter then i get it as 430cc. Don't quote me on it as its a long time since i was at school!

Yep, 431,67cc

thanks for your help guys.

"Just finishing a project" .......we need pictures please.

Agreed, any one who has a sum done for them must publish pictures.

Does it still look like this? hope you are doing some trials soon Rob.
