I beleve it has a 40mm piston, can I change the barrel and piston to 47 without changing the crank?
won't fit into the cases
The case is where the arm moving the piston is at right
Its a 47 NVM
cases for 40mm piston have a hole on top for cylinder to go in - cylinder for 47mm piston are also 47mm wide on inside, that makes the cylinder too wide to go into the hole in cases
