that is a tank of a bike.
Here is another one of my favorite stories.......
My best friend and I both came up with the historically bad idea of firing up a 1974 Ossa 250 Phantom dirt bike engine (minus the rest of the dirt bike) on his Garage floor. The engine still had it's lower electrics intact so all that was needed was a coil. Easy! We located one that would work and duct taped it to the side of the cylinder. After i did some creative wiring and points gapping, we had a nice fat blue spark appearing at the plug. The engine had no carburetor, just an open intake port which we sprayed a large amount of windshield de-icer ( mostly Methanol ) to see if we could get it to hit a few times. I held the engine, and my buddy punted the kick starter............WHACK!.............
What followed next was one of the most obscene and violent lessons in the world of physics I've ever witnessed: Instead of the 250cc Spanish motocrosser engine making a few revolutions, we were instantly greeted with 60 million instant RPM. An extremely loud 60 million RPM I might add. I instantly let go of the now awakened (and very pissed off) chunk of screaming aluminum while we both ran for opposite ends of the garage and watched it hop around, taking out pieces of the concrete floor in the process. After what seemed an eternity, the bastard finally exhausted its fuel supply, coming to rest on it's side.
To make matters worse we decided (for reasons that still aren't quite clear to me to this day) to pull this stunt at 12:30 AM. This of course awakened his sleeping Mom, the Former Marine. She was not amused by this and proceeded to verbally rip us new ones, in full USMC fashion.
