All of the twins swap, so if you want to put a 800 motor in a 650sx there is nothing stopping you. 750 BP motors are pretty good and can be had for about 25% the cost of a 800 motor. 750 SP motors are even cheaper than the BP motors. I fell if you had the money to waste on the performance gains of a 800 over a 750, then you wouldn't be doing it to a 650 hull. Go with a 750 motor and spend the left over money on carbs, pipe, prop and do what most people that have these skis do not do, tune it right.
