I do not know what the dwell or correct gap would;d be to get the correct dwell so I cannot help that way. You will need to google it or get the gap and/or dwell from a Yamaha or other such service center. To change point gap normally there is a screw which will loosen and allow the points to be moved (one side of the point assembly) so that with the cam that moves the point assembly apart on the middle of the high point the points can be set with the required gap between the open points to give the required dwell for coil primary saturation.,
