    The jetting will need slightly raising.
    The ignition timing might need a slight alter. Im unsure of standard timings on px's

    Almost sure the timing doesn't need touching if I remember right. Main should be around 102ish with exhaust, maybe higher if any breathing mods been done.

    Timing should be about right on the 125 setting, though you should have it strobed to get it right. Same goes for the cylinder head as well, 125 will do, but you should have a 150 one to get it right.

    Jetting wise, as Watson says 102-106 on the main will see you right
