    Oil pump mod?

    Someone told me about doing a mod for increased pressure. Anyone remember what it is?

    Yep.
    Tap a 1/8in npt thread into the top of the oil bypass plug. Thread in a plug that has a 1/4in hole drilled through it (I use a 13/64 but that is an uncommon size). Make sure you grind off some of the plug to clear the pump cover with enough gap between the top of the plug and cover so that oil can get into the drilled hole.

    If you live in cold climate, don't get on it until the oil is warmed up or you will see well over 100psi until the oil thins out. That much pressure caused my oil pressure sending units to fail and start leaking.
    Once warmed up, with the 13/64 hole I was seeing about 75 psi at 7k rpm.
