g'day i just grabed myself a 1976 bonny oil in frame. I was after a 650 but this will do to start with anyway. I was just wondering if the 750 motor from it will fit into a 650 frame? When i find a good one.
There is a difference in the head stays after 71 because of the changes to the head bolts and rocker boxes but it's not a big show stopper. Some of the latest heads have a different angle on the intake spigots that might cause some interference with the down tube of the frame and air filters but again, not a show stopper.
