General thought is that the Dellorto 22mm is best but surely the 20mm version would be better suited, for the standard 199cc engine,but apparently this is unavailable now. I have searched around and Mikuni do a VM22 set up for the cub amd a VM20. I am tempted to try the 20mm version but there are no base settings for this, has anyone tried the Mikuni on a cub?
