Im trying to find the right size cylinder for my engine and looking through different website there seems to be different size cylinders. first of, what is a bore cylinder eg. 47mm bore cylinder and 47mm piston. the one i saw from spookytooth had a cylinder kit but said it is only compatible with a grubee skyhawk because it had a different size bore size than any other cylinders. so yea just wanna get that terms down so i get the right one for my engine.
