Well if it's been confirmed that the 500 motor fits in the 250 frame, then I got news for you. That would mean the 650 motor will fit too. Believe it or not, but the outter dimensions of the 650 motor are smaller then the 500 making it lighter and slimmer. Imagine putting one of those puppies in the 250 frame.......... 71hp with about 48lb-ft of torque.
