re: 60 MPH...achieveable? Who cares?!? Let blueprint an engine!
Jim, Back when I use to rebuild my high reving BZMs. I use to remove the seals on the crank bearings. I found out that when I left them on the bearings my crank bearings would not get enough lubrication and evenually blow up from the heat. I'm not sure but doesn't the HT motors have crank seals that fit into the cases?
