My buddy just picked up a 91 superjet with a 61x cylinder on the stock 650 bottom so we are going to pick up a set of 62t cases for it as I have all the intake parts he needs from reeds to flame arrestors but I believe he has the stock 650 stator and flywheel and was wondering if they can be used with the 62t cases I know that 61x stator and flywheel can be used but I was unsure about the 650 parts maybe they are the same yes no?
