what is the difference between a 779 and a 809.... besides plated cylinders on the 809? will the top off of a stock 779 fit onto a ported crankshop 809? do they use the same bore? im pretty sure they are the same because the last guy who had my sled said they used a 779 bottom end with a 809 top end......im just trying to put this engine back to stock so I can just go riding with my kid......any info would be great......
