apparently, not all of the oil gets atomized in the case. there is a unit in the case that detects oil or rather no oil and kills the motor. when you get going fast and turn the oil will slosh away from this unit and kill the motor.
Yep I had the same problem with mine. Low oil sensor killed me in the corners all the time...its annoying. Not to highjack your thread or anything but where can we get performance parts for these clones?
I believe i had a simler problem it might be the air filter run it with out the air filter on some jacks and see if anything changes. Or it might not be getting enough fuel make sure u have a good flow of fuel running out of the gas tank.
