    Ported 1050, who's mark?

    Friend picked up a 99 slx last night. The cylinders and ext manifolds have been ported.

    Cylinders and pipe have PM 92 engraved. Assuming 92 is fuel octane, and PM is initials of who did the work.

    Anyone have an idea of who PM would be?

    Ski came from Missouri.

    K that would make sense.

    I'd take pics but she's already boxed up and heading to NY for a 1200 treatment.

    Gonna have a big parts list soon, bunch of little things to take care of.
