Could someone please tell me the difference between a powervalved 700 and a non powervalved 700 besides the jugs. Are the crankcases and the rods the same? Thanks
The motors are totally different; share no parts & have nothing in common from the carbs forward.

Thanks for the info. I never would have imagined they would be totally different. Would you tell me what the differences are? Thanks
The differences are...EVERYTHING....nothing in common.

pistons size different, cylinders, rods, bearings, crank, carbs, heads, crank case, electrical and exhaust all very different between these two motors.
