pm ur e/m address and I will show you what I do in that case.I run the 15* mount on both my karts and I can keep about 19oz in the motor, and it's crucial. Our sprint track has a series of sweeping RH turns that =270* which pins the oil up against the side cover for several seconds. After several seizures and broken rods that occurred in approx. the same area of the track past this section it became obvious what the problem was. Running more ounces and better oils with good zinc content has improved things greatly.
