If that Motorcycle was at Connecticut Dragway around 1970, I saw him run. As mentioned in the video, it spun the rear tire the entire length of the quarter mile. I believe he when through a new tire every 3 or 4 runs.
His bike is in Speedway Museum in Lincoln NE. This museum is well worth seeing. Buy a $20 T-shirt at store and get in free. BTW I'll check again for 409 shirts next time I'm in
