    Not sure if you’re talking about the “water cooled” ports in the exhaust
    housing or not. You pictures will tell all.
    About the only thing you can do to clean the cylinder without
    taking it apart would be spraying in WD-40 or similar, and
    using lots of compressed air. I would pour  some motor oil
    in the cylinder afterward.
