Here is something for you fast folks. If you have not seen it something to watch.
I could smell the rubber burning as I watched this. Must view on full screen.
You would have to wear a diaper to ride with this guy!
It sounds like the little car is running bad.....The reason it sounds like it is cutting is because of the revolution limiter.....it keeps the R.P.M. from going to high and blowing up the motor.........
Also: note at the very end, the sparks coming from the rear wheel rims as the tires burn down.
