Blown 212 or damage from over racing

[old shed finds]

Has axle anybody had a Coleman 200 turn to garbage after a day of hard running and racing?
Governor spring clipped so top speed RPM.
Bike now vibration... kinda pile of 500 bucks junk.
It's the stock engine 212 look a like...

Well kinda, the previous owner of mine had his stock engine last, I think he said a day or two.
But then again he also said they never put oil in the engine. ut:

When I bought it there was a brand new Predator 212 to go with it. :thumbsup:

You pull the governor on any stock motor and it can fail in a day of hard riding. The rods cant oil proper at high RPM and floating the valves can damage valve train.
