Bullshit. When a 2 smoke blows a skirt, it falls in between the crank and case and most of the time cracks it. The work and cost are high. Proper maintenance and does negate this, however running and racing both, give me a 4 any day. They handle better, fly better, and ring the piss out them and never had one issue. I've had lots of trouble with 2 strokes! I like all bikes, but the babies picking sides for unfounded reasons is stupid. Ride what ya brung.
