Now I'm really worried HELP! 1/7/7 UPDATE!

Doesn't the offset crank pin in the flywheels counterbalance the rod and piston? Don't know....just asking.

Don't know Geroge, but all of my RC model 2 strokes have counter ballanced cranks.

I wonder if a person could grind some weight off of the circular looking crank parts on the pin side, and essentially make them into counter ballanced cranks? It may hurt the performance a little because the crank case would not be as "stuffed", but given the option, I would go for smoother myself.
