my friend has a 84 cr80..he just bought a head that was bored to a 82cc..even though this has nothing 2 do with blasters what size piston does he have to get stock or over and if its over can u give me the right number over? thx guys
just measure the bore size then back figure it for piston size (als ocheck for wear or damage to the wall) instead of trying to calculate wha t you were told b ythe seller is the rated displacment result
