i would think it would depend on how long you ran at wide open throttle my buddy that built the 125 cart moters that won the nationals siad more oil more power for longer mm he ment giong from 50 to one to 32 to one on caster oil not the belray ,,,,, that saved it saved rings at 24 to32 to one i like belray hr1 at 50.to1 but it works great at 40 to 1 i like my kips valve to stay clean ..... and im not wide open all the time .... if you did that on my bike you would not live long enough to wear the rings out
I can understand in a shift-cart as they are running like 15,000 rpms without much airflow and the motors can easily fry at WFO for along time. Though I know the oil has NOTHING to do with the power, I can understand that it helps the motor last longer and maintain compression by keeping the rings lubed @ such high rpms.
