Remember the years?

Mine was failing at the small end, as have a number I have seen on here and elswhere.
Most likely a product of inexperience and lugging the motor too much, and opposite of what the sumo guys are doing to the engine.

So I guess it is prone to failure at high and low speeds, atleast on certain years?
