    Js550 cylinder jug

    I have an '82 js550. I bought it and tore it down. There are a few not too bad scratches but since I'm this far torn down I want nice cylinder walls. It has been bored out to the point that I'm looking to replace the jug and I'm wondering are all PP550 jugs compatible? If not, What's compatible with my 82 motor?

    All JS 550 piston port cylinders are basically the same.
