I want to buy a refurbished motor for my 86 js550. Would a js650 motor fit? Reason is, the 650 motors are cheaper then the 550 motors. Thanks

They will fit but you need an adapter plate for the engine to fit on a 550 engine plate.You also need the electrical box(cdi) that goes with the 650 engine.
