I'm working on building some boost bottles for some friends and myself and came to a small problem.
I understand the difference between the 66cc and 80cc rating based on where and how it's measured. Problem is technically there both correct it is a 66cc and 80cc engine. But depending what number you work off of the bottle size will be the right size or too big/small.
So does anyone know what number should be used for the the bottle volume. Is the head volume counted?
