The smoke in your video isn't "white" anyway- - - -it's the classic bluish smoke from burning oil. How many full throttle 30-50 MPH uphill acceleration runs have you done to seat the piston rings? According to Perfect Circle, a new set of rings needs a minimum of 10. Get the rings seated properly, and the smoke will disappear. These engines aren't fragile wallflowers- - - -they're as tough as woodpecker lips, so drive them like you stole 'em!
